Amazon DynamoDB Streams provides API actions for accessing streams and processing stream records. To learn more about application development with Streams, see Capturing Table Activity with DynamoDB Streams (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.html) in the Amazon DynamoDB Developer Guide.

The following are short descriptions of each low-level DynamoDB Streams action: 

DescribeStream - Returns detailed information about a particular stream.

GetRecords - Retrieves the stream records from within a shard.

GetShardIterator - Returns information on how to retrieve the streams

record from a shard with a given shard ID. 

ListStreams - Returns a list of all the streams associated with the current

AWS account and endpoint. The service client's operations are safe to be used concurrently. It is not safe to mutate any of the client's properties though.

func New 

func New(p client.ConfigProvider, cfgs ...*aws.Config) *DynamoDBStreams

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

Example: 

// Create a DynamoDBStreams client from just a session.
svc := dynamodbstreams.New(mySession)

// Create a DynamoDBStreams client with additional configuration
svc := dynamodbstreams.New(mySession, aws.NewConfig().WithRegion("us-west-2"))

func (*DynamoDBStreams) DescribeStream 

func (c *DynamoDBStreams) DescribeStream(input *DescribeStreamInput) (*DescribeStreamOutput, error)

DescribeStream API operation for Amazon DynamoDB Streams.

Returns information about a stream, including the current status of the stream, its Amazon Resource Name (ARN), the composition of its shards, and its corresponding DynamoDB table. 

You can call DescribeStream at a maximum rate of 10 times per second.

Each shard in the stream has a SequenceNumberRange associated with it.

If the SequenceNumberRange has a StartingSequenceNumber but no EndingSequenceNumber, then the shard is still open (able to receive more stream records). If both StartingSequenceNumber and EndingSequenceNumber are present, then that shard is closed and can no longer receive more data.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Amazon DynamoDB Streams's API operation DescribeStream for usage and error information.

Returned Error Codes:

  • ResourceNotFoundException The operation tried to access a nonexistent stream.

  • InternalServerError An error occurred on the server side.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/dynamodbstreams"
)

func main() {
	sess, err := session.NewSession()
	if err != nil {
		fmt.Println("failed to create session,", err)
		return
	}

	svc := dynamodbstreams.New(sess)

	params := &dynamodbstreams.DescribeStreamInput{
		StreamArn:             aws.String("StreamArn"), // Required
		ExclusiveStartShardId: aws.String("ShardId"),
		Limit:                 aws.Int64(1),
	}
	resp, err := svc.DescribeStream(params)

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

Output:

func (*DynamoDBStreams) DescribeStreamRequest 

func (c *DynamoDBStreams) DescribeStreamRequest(input *DescribeStreamInput) (req *request.Request, output *DescribeStreamOutput)

DescribeStreamRequest generates a "aws/request.Request" representing the client's request for the DescribeStream operation. The "output" return value can be used to capture response data after the request's "Send" method is called.

See DescribeStream for usage and error information.

Creating a request object using this method should be used when you want to inject custom logic into the request's lifecycle using a custom handler, or if you want to access properties on the request object before or after sending the request. If you just want the service response, call the DescribeStream method directly instead.

Note: You must call the "Send" method on the returned request object in order to execute the request. 

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

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

func (*DynamoDBStreams) GetRecords 

func (c *DynamoDBStreams) GetRecords(input *GetRecordsInput) (*GetRecordsOutput, error)

GetRecords API operation for Amazon DynamoDB Streams.

Retrieves the stream records from a given shard.

Specify a shard iterator using the ShardIterator parameter. The shard iterator specifies the position in the shard from which you want to start reading stream records sequentially. If there are no stream records available in the portion of the shard that the iterator points to, GetRecords returns an empty list. Note that it might take multiple calls to get to a portion of the shard that contains stream records. 

GetRecords can retrieve a maximum of 1 MB of data or 1000 stream records,

whichever comes first.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Amazon DynamoDB Streams's API operation GetRecords for usage and error information.

Returned Error Codes:

  • ResourceNotFoundException The operation tried to access a nonexistent stream.

  • LimitExceededException Your request rate is too high. The AWS SDKs for DynamoDB automatically retry requests that receive this exception. Your request is eventually successful, unless your retry queue is too large to finish. Reduce the frequency of requests and use exponential backoff. For more information, go to Error Retries and Exponential Backoff (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ErrorHandling.html#APIRetries) in the Amazon DynamoDB Developer Guide.

  • InternalServerError An error occurred on the server side.

  • ExpiredIteratorException The shard iterator has expired and can no longer be used to retrieve stream records. A shard iterator expires 15 minutes after it is retrieved using the GetShardIterator action.

  • TrimmedDataAccessException The operation attempted to read past the oldest stream record in a shard.

    In DynamoDB Streams, there is a 24 hour limit on data retention. Stream records whose age exceeds this limit are subject to removal (trimming) from the stream. You might receive a TrimmedDataAccessException if:

    You request a shard iterator with a sequence number older than the trim point (24 hours).

    You obtain a shard iterator, but before you use the iterator in a GetRecords request, a stream record in the shard exceeds the 24 hour period and is trimmed. This causes the iterator to access a record that no longer exists.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/dynamodbstreams"
)

func main() {
	sess, err := session.NewSession()
	if err != nil {
		fmt.Println("failed to create session,", err)
		return
	}

	svc := dynamodbstreams.New(sess)

	params := &dynamodbstreams.GetRecordsInput{
		ShardIterator: aws.String("ShardIterator"), // Required
		Limit:         aws.Int64(1),
	}
	resp, err := svc.GetRecords(params)

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

Output:

func (*DynamoDBStreams) GetRecordsRequest 

func (c *DynamoDBStreams) GetRecordsRequest(input *GetRecordsInput) (req *request.Request, output *GetRecordsOutput)

GetRecordsRequest generates a "aws/request.Request" representing the client's request for the GetRecords operation. The "output" return value can be used to capture response data after the request's "Send" method is called.

    fmt.Println(resp)
}

func (*DynamoDBStreams) GetShardIterator 

func (c *DynamoDBStreams) GetShardIterator(input *GetShardIteratorInput) (*GetShardIteratorOutput, error)

GetShardIterator API operation for Amazon DynamoDB Streams.

Returns a shard iterator. A shard iterator provides information about how to retrieve the stream records from within a shard. Use the shard iterator in a subsequent GetRecords request to read the stream records from the shard. 

A shard iterator expires 15 minutes after it is returned to the requester.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Amazon DynamoDB Streams's API operation GetShardIterator for usage and error information.
