Overview

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

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.

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

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

Using the Client

To Amazon DynamoDB Streams 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 Streams client DynamoDBStreams for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/dynamodbstreams/#New

func New 

func New(config aws.Config) *DynamoDBStreams

New creates a new instance of the DynamoDBStreams client with a config.

func (*DynamoDBStreams) DescribeStreamRequest 

func (c *DynamoDBStreams) DescribeStreamRequest(input *DescribeStreamInput) DescribeStreamRequest

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. 

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

func (*DynamoDBStreams) GetRecordsRequest 

func (c *DynamoDBStreams) GetRecordsRequest(input *GetRecordsInput) GetRecordsRequest

GetRecordsRequest returns a request value for making 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. 

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

func (*DynamoDBStreams) GetShardIteratorRequest 

func (c *DynamoDBStreams) GetShardIteratorRequest(input *GetShardIteratorInput) GetShardIteratorRequest

GetShardIteratorRequest returns a request value for making API operation for Amazon DynamoDB Streams.
