type DynamoDBAPI

type DynamoDBAPI interface {

	// This operation allows you to perform batch reads or writes on data stored in
	// DynamoDB, using PartiQL. Each read statement in a BatchExecuteStatement must
	// specify an equality condition on all key attributes. This enforces that each
	// SELECT statement in a batch returns at most a single item. The entire batch must
	// consist of either read statements or write statements, you cannot mix both in
	// one batch. A HTTP 200 response does not mean that all statements in the
	// BatchExecuteStatement succeeded. Error details for individual statements can be
	// found under the Error
	// (https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_BatchStatementResponse.html#DDB-Type-BatchStatementResponse-Error)
	// field of the BatchStatementResponse for each statement.

		optFns ...func(*dynamodb.Options)) (*dynamodb.BatchExecuteStatementOutput, error)

	// 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 returns 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 returns 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 dataset. If none of the
	// items can be processed due to insufficient provisioned throughput on all of the
	// tables in the request, then BatchGetItem returns 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
	// (https://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 Working
	// with Tables
	// (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/WorkingWithTables.html#CapacityUnitCalculations)
	// in the Amazon DynamoDB Developer Guide.

	// The BatchWriteItem operation puts or deletes multiple items in one or more
	// tables. A single call to BatchWriteItem can transmit up to 16MB of data over the
	// network, consisting of up to 25 item put or delete operations. While individual
	// items can be up to 400 KB once stored, it's important to note that an item's
	// representation might be greater than 400KB while being sent in DynamoDB's JSON
	// format for the API call. For more details on this distinction, see Naming Rules
	// and Data Types
	// (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.NamingRulesDataTypes.html).
	// 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. If none of the
	// items can be processed due to insufficient provisioned throughput on all of the
	// tables in the request, then BatchWriteItem returns 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
	// (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ErrorHandling.html#Programming.Errors.BatchOperations)
	// in the Amazon DynamoDB Developer Guide. With BatchWriteItem, you can efficiently
	// write or delete large amounts of data, such as from Amazon 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.
	//
	// * Your request contains at least two items with identical hash and
	// range keys (which essentially is two put operations).
	//
	// * 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.

	// Creates a backup for an existing table. Each time you create an on-demand
	// backup, the entire table data is backed up. There is no limit to the number of
	// on-demand backups that can be taken. When you create an on-demand backup, a time
	// marker of the request is cataloged, and the backup is created asynchronously, by
	// applying all changes until the time of the request to the last full table
	// snapshot. Backup requests are processed instantaneously and become available for
	// restore within minutes. You can call CreateBackup at a maximum rate of 50 times
