Overview

Package dynamodb provides the client and types for making API requests to Amazon DynamoDB.

Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling a distributed database, so that you don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling.

With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of request traffic. You can scale up or scale down your tables' throughput capacity without downtime or performance degradation, and use the AWS Management Console to monitor resource utilization and performance metrics.

DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is stored on solid state disks (SSDs) and automatically replicated across multiple Availability Zones in an AWS region, providing built-in high availability and data durability.

See https://docs.aws.amazon.com/goto/WebAPI/dynamodb-2012-08-10 for more information on this service.

See dynamodb package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/dynamodb/

Using the Client

To Amazon DynamoDB with the SDK use the New function to create a new service client. With that client you can make API requests to the service. These clients are safe to use concurrently.

See the SDK's documentation for more information on how to use the SDK. https://docs.aws.amazon.com/sdk-for-go/api/

See aws.Config documentation for more information on configuring SDK clients. https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config

See the Amazon DynamoDB client DynamoDB for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/dynamodb/#New

AttributeValue Marshaling and Unmarshaling Helpers

Utility helpers to marshal and unmarshal AttributeValue to and from Go types can be found in the dynamodbattribute sub package. This package provides has specialized functions for the common ways of working with AttributeValues. Such as map[string]*AttributeValue, []*AttributeValue, and directly with *AttributeValue. This is helpful for marshaling Go types for API operations such as PutItem, and unmarshaling Query and Scan APIs' responses.

See the dynamodbattribute package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/dynamodb/dynamodbattribute/

Expression Builders

The expression package provides utility types and functions to build DynamoDB expression for type safe construction of API ExpressionAttributeNames, and ExpressionAttribute Values.

The package represents the various DynamoDB Expressions as structs named accordingly. For example, ConditionBuilder represents a DynamoDB Condition Expression, an UpdateBuilder represents a DynamoDB Update Expression, and so on.

See the expression package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/dynamodb/expression/

type AttributeValueUpdate 

type AttributeValueUpdate struct {

	// Specifies how to perform the update. Valid values are PUT (default), DELETE,
	// and ADD. The behavior depends on whether the specified primary key already
	// exists in the table.
	//
	// If an item with the specified Key is found in the table:
	//
	//    * PUT - Adds the specified attribute to the item. If the attribute already
	//    exists, it is replaced by the new value.
	//
	//    * DELETE - If no value is specified, the attribute and its value are removed
	//    from the item. The data type of the specified value must match the existing
	//    value's data type.
	//
	// If a set of values is specified, then those values are subtracted from the
	//    old set. For example, if the attribute value was the set [a,b,c] and the
	//    DELETE action specified [a,c], then the final attribute value would be
	//    [b]. Specifying an empty set is an error.
	//
	//    * ADD - If the attribute does not already exist, then the attribute and
	//    its values are added to the item. If the attribute does exist, then the
	//    behavior of ADD depends on the data type of the attribute:
	//
	// If the existing attribute is a number, and if Value is also a number, then
	//    the Value is mathematically added to the existing attribute. If Value
	//    is a negative number, then it is subtracted from the existing attribute.
	//
	//  If you use ADD to increment or decrement a number value for an item that
	//    doesn't exist before the update, DynamoDB uses 0 as the initial value.
	//
	// In addition, if you use ADD to update an existing item, and intend to increment
	//    or decrement an attribute value which does not yet exist, DynamoDB uses
	//    0 as the initial value. For example, suppose that the item you want to
	//    update does not yet have an attribute named itemcount, but you decide
	//    to ADD the number 3 to this attribute anyway, even though it currently
	//    does not exist. DynamoDB will create the itemcount attribute, set its
	//    initial value to 0, and finally add 3 to it. The result will be a new
	//    itemcount attribute in the item, with a value of 3.
	//
	// If the existing data type is a set, and if the Value is also a set, then
	//    the Value is added to the existing set. (This is a set operation, not
	//    mathematical addition.) For example, if the attribute value was the set
	//    [1,2], and the ADD action specified [3], then the final attribute value
	//    would be [1,2,3]. An error occurs if an Add action is specified for a
	//    set attribute and the attribute type specified does not match the existing
	//    set type.
	//
	// Both sets must have the same primitive data type. For example, if the existing
	//    data type is a set of strings, the Value must also be a set of strings.
	//    The same holds true for number sets and binary sets.
	//
	// This action is only valid for an existing attribute whose data type is number
	//    or is a set. Do not use ADD for any other data types.
	//
	// If no item with the specified Key is found:
	//
	//    * PUT - DynamoDB creates a new item with the specified primary key, and
	//    then adds the attribute.
	//
	//    * DELETE - Nothing happens; there is no attribute to delete.
	//
	//    * ADD - DynamoDB creates an item with the supplied primary key and number
	//    (or set of numbers) for the attribute value. The only data types allowed
	//    are number and number set; no other data types can be specified.
	Action AttributeAction `type:"string" enum:"true"`

	// Represents the data for an attribute.
	//
	// Each attribute value is described as a name-value pair. The name is the data
	// type, and the value is the data itself.
	//
	// For more information, see Data TYpes (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.NamingRulesDataTypes.html#HowItWorks.DataTypes)
	// in the Amazon DynamoDB Developer Guide.
	Value *AttributeValue `type:"structure"`
	// contains filtered or unexported fields
}

For the UpdateItem operation, represents the attributes to be modified, the action to perform on each, and the new value for each.

You cannot use UpdateItem to update any primary key attributes. Instead, you will need to delete the item, and then use PutItem to create a new item with new attributes.

Attribute values cannot be null; string and binary type attributes must have lengths greater than zero; and set type attributes must not be empty. Requests with empty values will be rejected with a ValidationException exception. Please also see https://docs.aws.amazon.com/goto/WebAPI/dynamodb-2012-08-10/AttributeValueUpdate

type BatchGetItemInput 

type BatchGetItemInput struct {

	// A map of one or more table names and, for each table, a map that describes
	// one or more items to retrieve from that table. Each table name can be used
	// only once per BatchGetItem request.
	//
	// Each element in the map of items to retrieve consists of the following:
	//
	//    * ConsistentRead - If true, a strongly consistent read is used; if false
	//    (the default), an eventually consistent read is used.
	//
	//    * ExpressionAttributeNames - One or more substitution tokens for attribute
	//    names in the ProjectionExpression parameter. The following are some use
	//    cases for using ExpressionAttributeNames:
	//
	// To access an attribute whose name conflicts with a DynamoDB reserved word.
	//
	// To create a placeholder for repeating occurrences of an attribute name in
	//    an expression.
	//
	// To prevent special characters in an attribute name from being misinterpreted
	//    in an expression.
	//
	// Use the # character in an expression to dereference an attribute name. For
	//    example, consider the following attribute name:
	//
	// Percentile
	//
	// The name of this attribute conflicts with a reserved word, so it cannot be
	//    used directly in an expression. (For the complete list of reserved words,
	//    see Reserved Words (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ReservedWords.html)
	//    in the Amazon DynamoDB Developer Guide). To work around this, you could
	//    specify the following for ExpressionAttributeNames:
	//
	// {"#P":"Percentile"}
	//
	// You could then use this substitution in an expression, as in this example:
	//
	// #P = :val
	//
	// Tokens that begin with the : character are expression attribute values, which
	//    are placeholders for the actual value at runtime.
	//
	// For more information on expression attribute names, see Accessing Item Attributes
	//    (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.AccessingItemAttributes.html)
	//    in the Amazon DynamoDB Developer Guide.
	//
	//    * Keys - An array of primary key attribute values that define specific
	//    items in the table. For each primary key, you must provide all of the
	//    key attributes. For example, with a simple primary key, you only need
	//    to provide the partition key value. For a composite key, you must provide
	//    both the partition key value and the sort key value.
	//
	//    * ProjectionExpression - A string that identifies one or more attributes
	//    to retrieve from the table. These attributes can include scalars, sets,
	//    or elements of a JSON document. The attributes in the expression must
	//    be separated by commas.
	//
	// If no attribute names are specified, then all attributes will be returned.
	//    If any of the requested attributes are not found, they will not appear
	//    in the result.

	//    | contains | begins_with | size
	//
	// These function names are case-sensitive.

	Expected map[string]ExpectedAttributeValue `type:"map"`

	// One or more substitution tokens for attribute names in an expression. The
	// following are some use cases for using ExpressionAttributeNames:
	//
	//    * To access an attribute whose name conflicts with a DynamoDB reserved
	//    word.
	//
	//    * To create a placeholder for repeating occurrences of an attribute name
	//    in an expression.
	//
	//    * To prevent special characters in an attribute name from being misinterpreted
	//    in an expression.
	//
	// Use the # character in an expression to dereference an attribute name. For
	// example, consider the following attribute name:
	//
	//    * Percentile
	//
	// The name of this attribute conflicts with a reserved word, so it cannot be
	// used directly in an expression. (For the complete list of reserved words,
	// see Reserved Words (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ReservedWords.html)
	// in the Amazon DynamoDB Developer Guide). To work around this, you could specify
	// the following for ExpressionAttributeNames:
	//
	//    * {"#P":"Percentile"}
	//
	// You could then use this substitution in an expression, as in this example:
	//
	//    * #P = :val
	//
	// Tokens that begin with the : character are expression attribute values, which
	// are placeholders for the actual value at runtime.

	//
	// Available | Backordered | Discontinued
	//
	// You would first need to specify ExpressionAttributeValues as follows:
	//
	// { ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"}
	// }
	//
	// You could then use these values in an expression, such as this:

DynamoDB provides the API operation methods for making requests to Amazon DynamoDB. See this package's package overview docs for details on the service.

DynamoDB methods are safe to use concurrently. It is not safe to modify mutate any of the struct's properties though.

func New 

func New(config aws.Config) *DynamoDB

New creates a new instance of the DynamoDB client with a config. If additional configuration is needed for the client instance use the optional aws.Config parameter to add your extra config.

Example: 

// Create a DynamoDB client from just a config.
svc := dynamodb.New(myConfig)

// Create a DynamoDB client with additional configuration
svc := dynamodb.New(myConfig, aws.NewConfig().WithRegion("us-west-2"))

func (*DynamoDB) BatchGetItemPages 

func (c *DynamoDB) BatchGetItemPages(input *BatchGetItemInput, fn func(*BatchGetItemOutput, bool) bool) error

BatchGetItemPages iterates over the pages of a BatchGetItem operation, calling the "fn" function with the response data for each page. To stop iterating, return false from the fn function.

See BatchGetItem method for more information on how to use this operation.

Note: This operation can generate multiple requests to a service. 

// Example iterating over at most 3 pages of a BatchGetItem operation.
pageNum := 0
err := client.BatchGetItemPages(params,
    func(page *BatchGetItemOutput, lastPage bool) bool {
        pageNum++
        fmt.Println(page)
        return pageNum <= 3
    })

func (*DynamoDB) BatchGetItemPagesWithContext 

func (c *DynamoDB) BatchGetItemPagesWithContext(ctx aws.Context, input *BatchGetItemInput, fn func(*BatchGetItemOutput, bool) bool, opts ...aws.Option) error

BatchGetItemPagesWithContext same as BatchGetItemPages except it takes a Context and allows setting request options on the pages.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

func (*DynamoDB) BatchGetItemRequest 

func (c *DynamoDB) BatchGetItemRequest(input *BatchGetItemInput) BatchGetItemRequest

BatchGetItemRequest returns a request value for making API operation for Amazon DynamoDB.

The BatchGetItem operation returns the attributes of one or more items from one or more tables. You identify requested items by primary key.

A single operation can retrieve up to 16 MB of data, which can contain as many as 100 items. BatchGetItem will return a partial result if the response size limit is exceeded, the table's provisioned throughput is exceeded, or an internal processing failure occurs. If a partial result is returned, the operation returns a value for UnprocessedKeys. You can use this value to retry the operation starting with the next item to get.

If you request more than 100 items BatchGetItem will return a ValidationException with the message "Too many items requested for the BatchGetItem call".

For example, if you ask to retrieve 100 items, but each individual item is 300 KB in size, the system returns 52 items (so as not to exceed the 16 MB limit). It also returns an appropriate UnprocessedKeys value so you can get the next page of results. If desired, your application can include its own logic to assemble the pages of results into one data set.

If none of the items can be processed due to insufficient provisioned throughput on all of the tables in the request, then BatchGetItem will return a ProvisionedThroughputExceededException. If at least one of the items is successfully processed, then BatchGetItem completes successfully, while returning the keys of the unread items in UnprocessedKeys.

If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If you delay the batch operation using exponential backoff, the individual requests in the batch are much more likely to succeed.

For more information, see Batch Operations and Error Handling (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ErrorHandling.html#BatchOperations) in the Amazon DynamoDB Developer Guide.

By default, BatchGetItem performs eventually consistent reads on every table in the request. If you want strongly consistent reads instead, you can set ConsistentRead to true for any or all tables.

In order to minimize response latency, BatchGetItem retrieves items in parallel.

When designing your application, keep in mind that DynamoDB does not return items in any particular order. To help parse the response by item, include the primary key values for the items in your request in the ProjectionExpression parameter.

If a requested item does not exist, it is not returned in the result. Requests for nonexistent items consume the minimum read capacity units according to the type of read. For more information, see Capacity Units Calculations (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/WorkingWithTables.html#CapacityUnitCalculations) in the Amazon DynamoDB Developer Guide. 

// Example sending a request using the BatchGetItemRequest method.
req := client.BatchGetItemRequest(params)
resp, err := req.Send()
if err == nil {
    fmt.Println(resp)
}

func (*DynamoDB) BatchWriteItemRequest 

func (c *DynamoDB) BatchWriteItemRequest(input *BatchWriteItemInput) BatchWriteItemRequest

BatchWriteItemRequest returns a request value for making API operation for Amazon DynamoDB.

The BatchWriteItem operation puts or deletes multiple items in one or more tables. A single call to BatchWriteItem can write up to 16 MB of data, which can comprise as many as 25 put or delete requests. Individual items to be written can be as large as 400 KB.

BatchWriteItem cannot update items. To update items, use the UpdateItem action.

The individual PutItem and DeleteItem operations specified in BatchWriteItem are atomic; however BatchWriteItem as a whole is not. If any requested operations fail because the table's provisioned throughput is exceeded or an internal processing failure occurs, the failed operations are returned in the UnprocessedItems response parameter. You can investigate and optionally resend the requests. Typically, you would call BatchWriteItem in a loop. Each iteration would check for unprocessed items and submit a new BatchWriteItem request with those unprocessed items until all items have been processed.

Note that if none of the items can be processed due to insufficient provisioned throughput on all of the tables in the request, then BatchWriteItem will return a ProvisionedThroughputExceededException.

If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If you delay the batch operation using exponential backoff, the individual requests in the batch are much more likely to succeed.

For more information, see Batch Operations and Error Handling (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ErrorHandling.html#BatchOperations) in the Amazon DynamoDB Developer Guide.

With BatchWriteItem, you can efficiently write or delete large amounts of data, such as from Amazon Elastic MapReduce (EMR), or copy data from another database into DynamoDB. In order to improve performance with these large-scale operations, BatchWriteItem does not behave in the same way as individual PutItem and DeleteItem calls would. For example, you cannot specify conditions on individual put and delete requests, and BatchWriteItem does not return deleted items in the response.

If you use a programming language that supports concurrency, you can use threads to write items in parallel. Your application must include the necessary logic to manage the threads. With languages that don't support threading, you must update or delete the specified items one at a time. In both situations, BatchWriteItem performs the specified put and delete operations in parallel, giving you the power of the thread pool approach without having to introduce complexity into your application.

Parallel processing reduces latency, but each specified put and delete request consumes the same number of write capacity units whether it is processed in parallel or not. Delete operations on nonexistent items consume one write capacity unit.

If one or more of the following is true, DynamoDB rejects the entire batch write operation:

  • One or more tables specified in the BatchWriteItem request does not exist.

  • Primary key attributes specified on an item in the request do not match those in the corresponding table's primary key schema.

  • You try to perform multiple operations on the same item in the same BatchWriteItem request. For example, you cannot put and delete the same item in the same BatchWriteItem request.

  • There are more than 25 requests in the batch.

  • Any individual item in a batch exceeds 400 KB.

  • The total request size exceeds 16 MB.

    // Example sending a request using the BatchWriteItemRequest method. req := client.BatchWriteItemRequest(params) resp, err := req.Send() if err == nil { fmt.Println(resp) }

func (*DynamoDB) CreateTableRequest 

func (c *DynamoDB) CreateTableRequest(input *CreateTableInput) CreateTableRequest

CreateTableRequest returns a request value for making API operation for Amazon DynamoDB.

The CreateTable operation adds a new table to your account. In an AWS account, table names must be unique within each region. That is, you can have two tables with same name if you create the tables in different regions.

CreateTable is an asynchronous operation. Upon receiving a CreateTable request, DynamoDB immediately returns a response with a TableStatus of CREATING. After the table is created, DynamoDB sets the TableStatus to ACTIVE. You can perform read and write operations only on an ACTIVE table.

You can optionally define secondary indexes on the new table, as part of the CreateTable operation. If you want to create multiple tables with secondary indexes on them, you must create the tables sequentially. Only one table with secondary indexes can be in the CREATING state at any given time.

You can use the DescribeTable action to check the table status.

func (*DynamoDB) DeleteItemRequest 

func (c *DynamoDB) DeleteItemRequest(input *DeleteItemInput) DeleteItemRequest

DeleteItemRequest returns a request value for making API operation for Amazon DynamoDB.

Deletes a single item in a table by primary key. You can perform a conditional delete operation that deletes the item if it exists, or if it has an expected attribute value.

In addition to deleting an item, you can also return the item's attribute values in the same operation, using the ReturnValues parameter.

Unless you specify conditions, the DeleteItem is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

Conditional deletes are useful for deleting items only if specific conditions are met. If those conditions are met, DynamoDB performs the delete. Otherwise, the item is not deleted.

req := client.DeleteItemRequest(params)
resp, err := req.Send()

func (*DynamoDB) DeleteTableRequest 

func (c *DynamoDB) DeleteTableRequest(input *DeleteTableInput) DeleteTableRequest

DeleteTableRequest returns a request value for making API operation for Amazon DynamoDB.

The DeleteTable operation deletes a table and all of its items. After a DeleteTable request, the specified table is in the DELETING state until DynamoDB completes the deletion. If the table is in the ACTIVE state, you can delete it. If a table is in CREATING or UPDATING states, then DynamoDB returns a ResourceInUseException. If the specified table does not exist, DynamoDB returns a ResourceNotFoundException. If table is already in the DELETING state, no error is returned.

DynamoDB might continue to accept data read and write operations, such as GetItem and PutItem, on a table in the DELETING state until the table deletion is complete.

When you delete a table, any indexes on that table are also deleted.

If you have DynamoDB Streams enabled on the table, then the corresponding stream on that table goes into the DISABLED state, and the stream is automatically deleted after 24 hours.

Use the DescribeTable action to check the status of the table.

func (*DynamoDB) DescribeLimitsRequest 

func (c *DynamoDB) DescribeLimitsRequest(input *DescribeLimitsInput) DescribeLimitsRequest

DescribeLimitsRequest returns a request value for making API operation for Amazon DynamoDB.

Returns the current provisioned-capacity limits for your AWS account in a region, both for the region as a whole and for any one DynamoDB table that you create there.

When you establish an AWS account, the account has initial limits on the maximum read capacity units and write capacity units that you can provision across all of your DynamoDB tables in a given region. Also, there are per-table limits that apply when you create a table there. For more information, see Limits (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html) page in the Amazon DynamoDB Developer Guide.

Although you can increase these limits by filing a case at AWS Support Center (https://console.aws.amazon.com/support/home#/), obtaining the increase is not instantaneous. The DescribeLimits action lets you write code to compare the capacity you are currently using to those limits imposed by your account so that you have enough time to apply for an increase before you hit a limit.

For example, you could use one of the AWS SDKs to do the following:

Call DescribeLimits for a particular region to obtain your current account limits on provisioned capacity there.

Create a variable to hold the aggregate read capacity units provisioned for all your tables in that region, and one to hold the aggregate write capacity units. Zero them both.

Call ListTables to obtain a list of all your DynamoDB tables.

For each table name listed by ListTables, do the following:

Call DescribeTable with the table name.

Use the data returned by DescribeTable to add the read capacity units and write capacity units provisioned for the table itself to your variables.

If the table has one or more global secondary indexes (GSIs), loop over these GSIs and add their provisioned capacity values to your variables as well.

Report the account limits for that region returned by DescribeLimits, along with the total current provisioned capacity levels you have calculated.

This will let you see whether you are getting close to your account-level limits.

The per-table limits apply only when you are creating a new table. They restrict the sum of the provisioned capacity of the new table itself and all its global secondary indexes.

For existing tables and their GSIs, DynamoDB will not let you increase provisioned capacity extremely rapidly, but the only upper limit that applies is that the aggregate provisioned capacity over all your tables and GSIs cannot exceed either of the per-account limits.

DescribeLimits should only be called periodically. You can expect throttling errors if you call it more than once in a minute.

The DescribeLimits Request element has no content.

func (*DynamoDB) PutItemRequest 

func (c *DynamoDB) PutItemRequest(input *PutItemInput) PutItemRequest

PutItemRequest returns a request value for making API operation for Amazon DynamoDB.

Creates a new item, or replaces an old item with a new item. If an item that has the same primary key as the new item already exists in the specified table, the new item completely replaces the existing item. You can perform a conditional put operation (add a new item if one with the specified primary key doesn't exist), or replace an existing item if it has certain attribute values. You can return the item's attribute values in the same operation, using the ReturnValues parameter.

This topic provides general information about the PutItem API.

For information on how to call the PutItem API using the AWS SDK in specific languages, see the following: 

PutItem in the AWS Command Line Interface  (http://docs.aws.amazon.com/goto/aws-cli/dynamodb-2012-08-10/PutItem)

PutItem in the AWS SDK for Python  (http://docs.aws.amazon.com/goto/boto3/dynamodb-2012-08-10/PutItem)

PutItem in the AWS SDK for Ruby V2  (http://docs.aws.amazon.com/goto/SdkForRubyV2/dynamodb-2012-08-10/PutItem)

When you add an item, the primary key attribute(s) are the only required attributes. Attribute values cannot be null. String and Binary type attributes must have lengths greater than zero. Set type attributes cannot be empty. Requests with empty values will be rejected with a ValidationException exception.

To prevent a new item from replacing an existing item, use a conditional expression that contains the attribute_not_exists function with the name of the attribute being used as the partition key for the table. Since every record must contain that attribute, the attribute_not_exists function will only succeed if no matching item exists.

For more information about PutItem, see Working with Items (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/WorkingWithItems.html) in the Amazon DynamoDB Developer Guide.

func (*DynamoDB) QueryRequest 

func (c *DynamoDB) QueryRequest(input *QueryInput) QueryRequest

QueryRequest returns a request value for making API operation for Amazon DynamoDB.

The Query operation finds items based on primary key values. You can query any table or secondary index that has a composite primary key (a partition key and a sort key).

Use the KeyConditionExpression parameter to provide a specific value for the partition key. The Query operation will return all of the items from the table or index with that partition key value. You can optionally narrow the scope of the Query operation by specifying a sort key value and a comparison operator in KeyConditionExpression. To further refine the Query results, you can optionally provide a FilterExpression. A FilterExpression determines which items within the results should be returned to you. All of the other results are discarded.

A Query operation always returns a result set. If no matching items are found, the result set will be empty. Queries that do not return results consume the minimum number of read capacity units for that type of read operation.

DynamoDB calculates the number of read capacity units consumed based on item size, not on the amount of data that is returned to an application. The number of capacity units consumed will be the same whether you request all of the attributes (the default behavior) or just some of them (using a projection expression). The number will also be the same whether or not you use a FilterExpression.

Query results are always sorted by the sort key value. If the data type of the sort key is Number, the results are returned in numeric order; otherwise, the results are returned in order of UTF-8 bytes. By default, the sort order is ascending. To reverse the order, set the ScanIndexForward parameter to false.

A single Query operation will read up to the maximum number of items set (if using the Limit parameter) or a maximum of 1 MB of data and then apply any filtering to the results using FilterExpression. If LastEvaluatedKey is present in the response, you will need to paginate the result set. For more information, see Paginating the Results (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.html#Query.Pagination) in the Amazon DynamoDB Developer Guide.

FilterExpression is applied after a Query finishes, but before the results are returned. A FilterExpression cannot contain partition key or sort key attributes. You need to specify those attributes in the KeyConditionExpression.

A Query operation can return an empty result set and a LastEvaluatedKey if all the items read for the page of results are filtered out.

You can query a table, a local secondary index, or a global secondary index. For a query on a table or on a local secondary index, you can set the ConsistentRead parameter to true and obtain a strongly consistent result. Global secondary indexes support eventually consistent reads only, so do not specify ConsistentRead when querying a global secondary index. 

// Example sending a request using the QueryRequest method.
req := client.QueryRequest(params)
resp, err := req.Send()
if err == nil {
    fmt.Println(resp)
}

func (*DynamoDB) ScanRequest 

func (c *DynamoDB) ScanRequest(input *ScanInput) ScanRequest

ScanRequest returns a request value for making API operation for Amazon DynamoDB.

The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. To have DynamoDB return fewer items, you can provide a FilterExpression operation.

If the total number of scanned items exceeds the maximum data set size limit of 1 MB, the scan stops and results are returned to the user as a LastEvaluatedKey value to continue the scan in a subsequent operation. The results also include the number of items exceeding the limit. A scan can result in no table data meeting the filter criteria.

A single Scan operation will read up to the maximum number of items set (if using the Limit parameter) or a maximum of 1 MB of data and then apply any filtering to the results using FilterExpression. If LastEvaluatedKey is present in the response, you will need to paginate the result set. For more information, see Paginating the Results (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Scan.html#Scan.Pagination) in the Amazon DynamoDB Developer Guide.

Scan operations proceed sequentially; however, for faster performance on a large table or secondary index, applications can request a parallel Scan operation by providing the Segment and TotalSegments parameters. For more information, see Parallel Scan (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Scan.html#Scan.ParallelScan) in the Amazon DynamoDB Developer Guide.

Scan uses eventually consistent reads when accessing the data in a table; therefore, the result set might not include the changes to data in the table immediately before the operation began. If you need a consistent copy of the data, as of the time that the Scan begins, you can set the ConsistentRead parameter to true. 

// Example sending a request using the ScanRequest method.
req := client.ScanRequest(params)

func (*DynamoDB) UpdateTableRequest 

func (c *DynamoDB) UpdateTableRequest(input *UpdateTableInput) UpdateTableRequest

UpdateTableRequest returns a request value for making API operation for Amazon DynamoDB.

Modifies the provisioned throughput settings, global secondary indexes, or DynamoDB Streams settings for a given table.

You can only perform one of the following operations at once:

  • Modify the provisioned throughput settings of the table.

  • Enable or disable Streams on the table.

  • Remove a global secondary index from the table.

  • Create a new global secondary index on the table. Once the index begins backfilling, you can use UpdateTable to perform other operations.

UpdateTable is an asynchronous operation; while it is executing, the table status changes from ACTIVE to UPDATING. While it is UPDATING, you cannot issue another UpdateTable request. When the table returns to the ACTIVE state, the UpdateTable operation is complete. 

// Example sending a request using the UpdateTableRequest method.
req := client.UpdateTableRequest(params)

func (*DynamoDB) UpdateTimeToLiveRequest 

func (c *DynamoDB) UpdateTimeToLiveRequest(input *UpdateTimeToLiveInput) UpdateTimeToLiveRequest

UpdateTimeToLiveRequest returns a request value for making API operation for Amazon DynamoDB.

The UpdateTimeToLive method will enable or disable TTL for the specified table. A successful UpdateTimeToLive call returns the current TimeToLiveSpecification; it may take up to one hour for the change to fully process. Any additional UpdateTimeToLive calls for the same table during this one hour duration result in a ValidationException.

TTL compares the current time in epoch time format to the time stored in the TTL attribute of an item. If the epoch time value stored in the attribute is less than the current time, the item is marked as expired and subsequently deleted.

The epoch time format is the number of seconds elapsed since 12:00:00 AM January 1st, 1970 UTC.

DynamoDB deletes expired items on a best-effort basis to ensure availability of throughput for other data operations.

DynamoDB typically deletes expired items within two days of expiration. The exact duration within which an item gets deleted after expiration is specific to the nature of the workload. Items that have expired and not been deleted will still show up in reads, queries, and scans.

As items are deleted, they are removed from any Local Secondary Index and Global Secondary Index immediately in the same eventually consistent way as a standard delete operation.

For more information, see Time To Live (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/TTL.html) in the Amazon DynamoDB Developer Guide. 

// Example sending a request using the UpdateTimeToLiveRequest method.
req := client.UpdateTimeToLiveRequest(params)
resp, err := req.Send()
if err == nil {
    fmt.Println(resp)

type ExpectedAttributeValue 

type ExpectedAttributeValue struct {

	// One or more values to evaluate against the supplied attribute. The number
	// of values in the list depends on the ComparisonOperator being used.
	//
	// For type Number, value comparisons are numeric.
	//
	// String value comparisons for greater than, equals, or less than are based
	// on ASCII character code values. For example, a is greater than A, and a is
	// greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters
	// (http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters).
	//
	// For Binary, DynamoDB treats each byte of the binary data as unsigned when
	// it compares binary values.
	//
	// For information on specifying data types in JSON, see JSON Data Format (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DataFormat.html)
	// in the Amazon DynamoDB Developer Guide.
	AttributeValueList []AttributeValue `type:"list"`

	// A comparator for evaluating attributes in the AttributeValueList. For example,
	// equals, greater than, less than, etc.
	//
	// The following comparison operators are available:
	//
	// EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS |
	// BEGINS_WITH | IN | BETWEEN
	//
	// The following are descriptions of each comparison operator.
	//
	//    * EQ : Equal. EQ is supported for all data types, including lists and
	//    maps.
	//
	// AttributeValueList can contain only one AttributeValue element of type String,
	//    Number, Binary, String Set, Number Set, or Binary Set. If an item contains
	//    an AttributeValue element of a different type than the one provided in
	//    the request, the value does not match. For example, {"S":"6"} does not
	//    equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.
	//
	//    * NE : Not equal. NE is supported for all data types, including lists
	//    and maps.
	//
	//    * AttributeValueList can contain only one AttributeValue of type String,
	//    Number, Binary, String Set, Number Set, or Binary Set. If an item contains
	//    an AttributeValue of a different type than the one provided in the request,
	//    the value does not match. For example, {"S":"6"} does not equal {"N":"6"}.
	//    Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.
	//
	//    * LE : Less than or equal.
	//
	// AttributeValueList can contain only one AttributeValue element of type String,
	// Number, or Binary (not a set type). If an item contains an AttributeValue
	// element of a different type than the one provided in the request, the value
	// does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"}
	// does not compare to {"NS":["6", "2", "1"]}.
	//
	// LT: Less than.
	//
	// AttributeValueListcan contain only one AttributeValueof type String, Number, or Binary (not a set type). If an item contains an
	// AttributeValueelement of a different type than the one provided in the request, the value
	// does not match. For example, {"S":"6"}does not equal {"N":"6"}. Also, {"N":"6"}does not compare to {"NS":["6", "2", "1"]}
	ComparisonOperator ComparisonOperator `type:"string" enum:"true"`

	// Causes DynamoDB to evaluate the value before attempting a conditional operation:
	//
	//    * If Exists is true, DynamoDB will check to see if that attribute value
	//    already exists in the table. If it is found, then the operation succeeds.
	//    If it is not found, the operation fails with a ConditionalCheckFailedException.
	//
	//    * If Exists is false, DynamoDB assumes that the attribute value does not
	//    exist in the table. If in fact the value does not exist, then the assumption
	//    is valid and the operation succeeds. If the value is found, despite the
	//    assumption that it does not exist, the operation fails with a ConditionalCheckFailedException.
	//
	// The default setting for Exists is true. If you supply a Value all by itself,
	// DynamoDB assumes the attribute exists: You don't have to set Exists to true,
	// because it is implied.
	//
	// DynamoDB returns a ValidationException if:
	//
	//    * Exists is true but there is no Value to check. (You expect a value to
	//    exist, but don't specify what that value is.)
	//
	//    * Exists is false but you also provide a Value. (You cannot expect an
	//    attribute to have a value, while also expecting it not to exist.)
	Exists *bool `type:"boolean"`

	// Represents the data for the expected attribute.
	//
	// Each attribute value is described as a name-value pair. The name is the data
	// type, and the value is the data itself.
	//
	// For more information, see Data Types (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.NamingRulesDataTypes.html#HowItWorks.DataTypes)
	// in the Amazon DynamoDB Developer Guide.
	Value *AttributeValue `type:"structure"`
	// contains filtered or unexported fields
}

Represents a condition to be compared with an attribute value. This condition can be used with DeleteItem, PutItem or UpdateItem operations; if the comparison evaluates to true, the operation succeeds; if not, the operation fails. You can use ExpectedAttributeValue in one of two different ways:

  • Use AttributeValueList to specify one or more values to compare against an attribute. Use ComparisonOperator to specify how you want to perform the comparison. If the comparison evaluates to true, then the conditional operation succeeds.

  • Use Value to specify a value that DynamoDB will compare against an attribute. If the values match, then ExpectedAttributeValue evaluates to true and the conditional operation succeeds. Optionally, you can also set Exists to false, indicating that you do not expect to find the attribute value in the table. In this case, the conditional operation succeeds only if the comparison evaluates to false.

Value and Exists are incompatible with AttributeValueList and ComparisonOperator. Note that if you use both sets of parameters at once, DynamoDB will return a ValidationException exception. Please also see https://docs.aws.amazon.com/goto/WebAPI/dynamodb-2012-08-10/ExpectedAttributeValue

}

Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map. Please also see https://docs.aws.amazon.com/goto/WebAPI/dynamodb-2012-08-10/KeySchemaElement

	//
	//    * To prevent special characters in an attribute name from being misinterpreted
	//    in an expression.
	//
	// Use the # character in an expression to dereference an attribute name. For
	// example, consider the following attribute name:
	//
	//    * Percentile
	//
	// The name of this attribute conflicts with a reserved word, so it cannot be

	//    * Backfilling - If true, then the index is currently in the backfilling
	//    phase. Backfilling occurs only when a new global secondary index is added

	//    with data from the table. (This attribute does not appear for indexes
	//    that were created during a CreateTable operation.)
	//
	//    * IndexName - The name of the global secondary index.
	//
	//    * IndexSizeBytes - The total size of the global secondary index, in bytes.

	//
	// The sort key of an item is also known as its range attribute. The term "range

	// One or more substitution tokens for attribute names in an expression. The

	//
	//    * To access an attribute whose name conflicts with a DynamoDB reserved
	//    word.
	//
	//    * To create a placeholder for repeating occurrences of an attribute name
	//    in an expression.
	//
	//    * To prevent special characters in an attribute name from being misinterpreted
	//    in an expression.
	//
	// Use the # character in an expression to dereference an attribute name. For
	// example, consider the following attribute name:
	//
	//    * Percentile
	//
	// The name of this attribute conflicts with a reserved word, so it cannot be

	// see Reserved Words (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ReservedWords.html)
	// in the Amazon DynamoDB Developer Guide). To work around this, you could specify
	// the following for ExpressionAttributeNames:
	//
	//    * {"#P":"Percentile"}
	//
	// You could then use this substitution in an expression, as in this example:
	//
	//    * #P = :val
	//
	// Tokens that begin with the : character are expression attribute values, which
	// are placeholders for the actual value at runtime.

	// Available | Backordered | Discontinued
	//
	// You would first need to specify ExpressionAttributeValues as follows:
	//

	// }
	//
	// You could then use these values in an expression, such as this:

	ReturnItemCollectionMetrics ReturnItemCollectionMetrics `type:"string" enum:"true"`

	// Use ReturnValues if you want to get the item attributes as they appear before
	// or after they are updated. For UpdateItem, the valid values are:

	//    nothing is returned. (This setting is the default for ReturnValues.)
	//
	//    * ALL_OLD - Returns all of the attributes of the item, as they appeared

	//
	//    * UPDATED_OLD - Returns only the updated attributes, as they appeared
	//    before the UpdateItem operation.

	//
	//    * UPDATED_NEW - Returns only the updated attributes, as they appear after

	// The name of the table containing the item to update.

	// TableName is a required field
	TableName *string `min:"3" type:"string" required:"true"`

	// An expression that defines one or more attributes to be updated, the action
	// to be performed on them, and new value(s) for them.
	//
	// The following action values are available for UpdateExpression.
	//
	//    * SET - Adds one or more attributes and values to an item. If any of these
	//    attribute already exist, they are replaced by the new values. You can
	//    also use SET to add or subtract from an attribute that is of type Number.
	//    For example: SET myNum = myNum + :val
	//
	// SET supports the following functions:
	//
	// if_not_exists (path, operand) - if the item does not contain an attribute
	//    at the specified path, then if_not_exists evaluates to operand; otherwise,
	//    it evaluates to path. You can use this function to avoid overwriting an
	//    attribute that may already be present in the item.
	//
	// list_append (operand, operand) - evaluates to a list with a new element added
	//    to it. You can append the new element to the start or the end of the list
	//    by reversing the order of the operands.
	//
	// These function names are case-sensitive.
	//
	//    * REMOVE - Removes one or more attributes from an item.
	//
	//    * ADD - Adds the specified value to the item, if the attribute does not
	//    already exist. If the attribute does exist, then the behavior of ADD depends
	//    on the data type of the attribute:
	//
	// If the existing attribute is a number, and if Value is also a number, then
	//    Value is mathematically added to the existing attribute. If Value is a
	//    negative number, then it is subtracted from the existing attribute.
	//
	// If you use ADD to increment or decrement a number value for an item that
	//    doesn't exist before the update, DynamoDB uses 0 as the initial value.
	//
	// Similarly, if you use ADD for an existing item to increment or decrement
	//    an attribute value that doesn't exist before the update, DynamoDB uses
	//    0 as the initial value. For example, suppose that the item you want to
	//    update doesn't have an attribute named itemcount, but you decide to ADD
	//    the number 3 to this attribute anyway. DynamoDB will create the itemcount
	//    attribute, set its initial value to 0, and finally add 3 to it. The result
	//    will be a new itemcount attribute in the item, with a value of 3.
	//
	// If the existing data type is a set and if Value is also a set, then Value
	//    is added to the existing set. For example, if the attribute value is the
	//    set [1,2], and the ADD action specified [3], then the final attribute
	//    value is [1,2,3]. An error occurs if an ADD action is specified for a
	//    set attribute and the attribute type specified does not match the existing
	//    set type.
	//
	// Both sets must have the same primitive data type. For example, if the existing
	//    data type is a set of strings, the Value must also be a set of strings.
	//
	// The ADD action only supports Number and set data types. In addition, ADD
	//    can only be used on top-level attributes, not nested attributes.
	//
	//    * DELETE - Deletes an element from a set.
	//
	// If a set of values is specified, then those values are subtracted from the
	//    old set. For example, if the attribute value was the set [a,b,c] and the
	//    DELETE action specifies [a,c], then the final attribute value is [b].
	//    Specifying an empty set is an error.
	//
	// The DELETE action only supports set data types. In addition, DELETE can only
	//    be used on top-level attributes, not nested attributes.
	//
	// You can have many actions in a single expression, such as the following:
	// SET a=:value1, b=:value2 DELETE :value3, :value4, :value5
	//
