Interface AmazonDynamoDBStreamsAsync

All Superinterfaces:
AmazonDynamoDBStreams
All Known Implementing Classes:
AbstractAmazonDynamoDBStreamsAsync, AmazonDynamoDBStreamsAsyncClient

public interface AmazonDynamoDBStreamsAsync extends AmazonDynamoDBStreams
Interface for accessing Amazon DynamoDB Streams asynchronously. Each asynchronous method will return a Java Future object representing the asynchronous operation; overloads which accept an AsyncHandler can be used to receive notification when an asynchronous operation completes.

Amazon DynamoDB Streams

This is the Amazon DynamoDB Streams API Reference. This guide describes the low-level API actions for accessing streams and processing stream records. For information about application development with DynamoDB Streams, see the Amazon DynamoDB Developer Guide.

Note that this document is intended for use with the following DynamoDB documentation:

The following are short descriptions of each low-level DynamoDB Streams API action, organized by function.

  • 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.

  • Method Details

    • describeStreamAsync

      Future<DescribeStreamResult> describeStreamAsync(DescribeStreamRequest 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, the that shared is closed and can no longer receive more data.

      Parameters:
      describeStreamRequest - Represents the input of a DescribeStream operation.
      Returns:
      A Java Future containing the result of the DescribeStream operation returned by the service.
    • describeStreamAsync

      Future<DescribeStreamResult> describeStreamAsync(DescribeStreamRequest describeStreamRequest, AsyncHandler<DescribeStreamRequest,DescribeStreamResult> asyncHandler)

      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, the that shared is closed and can no longer receive more data.

      Parameters:
      describeStreamRequest - Represents the input of a DescribeStream operation.
      asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.
      Returns:
      A Java Future containing the result of the DescribeStream operation returned by the service.
    • getRecordsAsync

      Future<GetRecordsResult> getRecordsAsync(GetRecordsRequest getRecordsRequest)

      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 2000 stream records, whichever comes first.

      Parameters:
      getRecordsRequest - Represents the input of a GetRecords operation.
      Returns:
      A Java Future containing the result of the GetRecords operation returned by the service.
    • getRecordsAsync

      Future<GetRecordsResult> getRecordsAsync(GetRecordsRequest getRecordsRequest, AsyncHandler<GetRecordsRequest,GetRecordsResult> asyncHandler)

      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 2000 stream records, whichever comes first.

      Parameters:
      getRecordsRequest - Represents the input of a GetRecords operation.
      asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.
      Returns:
      A Java Future containing the result of the GetRecords operation returned by the service.
    • getShardIteratorAsync

      Future<GetShardIteratorResult> getShardIteratorAsync(GetShardIteratorRequest getShardIteratorRequest)

      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.

      Parameters:
      getShardIteratorRequest - Represents the input of a GetShardIterator operation.
      Returns:
      A Java Future containing the result of the GetShardIterator operation returned by the service.
    • getShardIteratorAsync

      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.

      Parameters:
      getShardIteratorRequest - Represents the input of a GetShardIterator operation.
      asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.
      Returns:
      A Java Future containing the result of the GetShardIterator operation returned by the service.
    • listStreamsAsync

      Future<ListStreamsResult> listStreamsAsync(ListStreamsRequest listStreamsRequest)

      Returns an array of stream ARNs associated with the current account and endpoint. If the TableName parameter is present, then ListStreams will return only the streams ARNs for that table.

      You can call ListStreams at a maximum rate of 5 times per second.

      Parameters:
      listStreamsRequest - Represents the input of a ListStreams operation.
      Returns:
      A Java Future containing the result of the ListStreams operation returned by the service.
    • listStreamsAsync

      Future<ListStreamsResult> listStreamsAsync(ListStreamsRequest listStreamsRequest, AsyncHandler<ListStreamsRequest,ListStreamsResult> asyncHandler)

      Returns an array of stream ARNs associated with the current account and endpoint. If the TableName parameter is present, then ListStreams will return only the streams ARNs for that table.

      You can call ListStreams at a maximum rate of 5 times per second.

      Parameters:
      listStreamsRequest - Represents the input of a ListStreams operation.
      asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.
      Returns:
      A Java Future containing the result of the ListStreams operation returned by the service.
