Interface AmazonDynamoDBStreamsAsync

All Superinterfaces:

AmazonDynamoDBStreams

All Known Implementing Classes:

AbstractAmazonDynamoDBStreamsAsync, AmazonDynamoDBStreamsAsyncClient

@Generated(value="com.amazonaws:aws-java-sdk-code-generator")
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.

Note: Do not directly implement this interface, new methods are added to it regularly. Extend from AbstractAmazonDynamoDBStreamsAsync instead.

Amazon DynamoDB

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 in the Amazon DynamoDB Developer Guide.

Method Detail

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, then that shard 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, then that shard 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 1000 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.

AWS API Documentation

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 1000 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.

                                                     AsyncHandler<GetShardIteratorRequest,GetShardIteratorResult> asyncHandler)

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:

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.
