Abstract implementation of AmazonDynamoDBStreamsAsync. Convenient method forms pass through to the corresponding overload that takes a request object and an AsyncHandler, which throws an UnsupportedOperationException.

Method Detail

describeStreamAsync

public Future<DescribeStreamResult> describeStreamAsync(DescribeStreamRequest request)

Description copied from interface: AmazonDynamoDBStreamsAsync

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.

Specified by:

describeStreamAsync in interface AmazonDynamoDBStreamsAsync

Parameters:

request - Represents the input of a DescribeStream operation.

Returns:

A Java Future containing the result of the DescribeStream operation returned by the service.

                                               AsyncHandler<DescribeStreamRequest,DescribeStreamResult> asyncHandler)

Description copied from interface: AmazonDynamoDBStreamsAsync

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.

Specified by:

describeStreamAsync in interface AmazonDynamoDBStreamsAsync

Parameters:

request - 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

public Future<GetRecordsResult> getRecordsAsync(GetRecordsRequest request)

Description copied from interface: AmazonDynamoDBStreamsAsync

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.

Specified by:

getRecordsAsync in interface AmazonDynamoDBStreamsAsync

Parameters:

request - Represents the input of a GetRecords operation.

Returns:

A Java Future containing the result of the GetRecords operation returned by the service.

getRecordsAsync

public Future<GetRecordsResult> getRecordsAsync(GetRecordsRequest request,
                                       AsyncHandler<GetRecordsRequest,GetRecordsResult> asyncHandler)

Description copied from interface: AmazonDynamoDBStreamsAsync

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.

Specified by:

getRecordsAsync in interface AmazonDynamoDBStreamsAsync

Parameters:

request - 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

public Future<GetShardIteratorResult> getShardIteratorAsync(GetShardIteratorRequest request)

Description copied from interface: AmazonDynamoDBStreamsAsync

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.

Specified by:

getShardIteratorAsync in interface AmazonDynamoDBStreamsAsync

Parameters:

request - Represents the input of a GetShardIterator operation.

Returns:

A Java Future containing the result of the GetShardIterator operation returned by the service.

Description copied from interface: AmazonDynamoDBStreamsAsync

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.

Specified by:

getShardIteratorAsync in interface AmazonDynamoDBStreamsAsync

Parameters:

request - 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

public Future<ListStreamsResult> listStreamsAsync(ListStreamsRequest request)

Description copied from interface: AmazonDynamoDBStreamsAsync

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.

Specified by:

listStreamsAsync in interface AmazonDynamoDBStreamsAsync

Parameters:

request - Represents the input of a ListStreams operation.

Returns:

A Java Future containing the result of the ListStreams operation returned by the service.
