software.amazon.awssdk.auth.credentials.DefaultCredentialsProvider.static DynamoDBStreamsAsyncClientBuilder builder()
DynamoDBStreamsAsyncClient.default CompletableFuture<DescribeStreamResponse> describeStream(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.
describeStreamRequest - Represents the input of a DescribeStream operation.default CompletableFuture<DescribeStreamResponse> describeStream(Consumer<DescribeStreamRequest.Builder> 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.
This is a convenience which creates an instance of the DescribeStreamRequest.Builder avoiding the need to
create one manually via DescribeStreamRequest.builder()
describeStreamRequest - A Consumer that will call methods on DescribeStreamInput.Builder to create a request.
Represents the input of a DescribeStream operation.default DescribeStreamPublisher describeStreamPaginator(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.

This is a variant of
describeStream(software.amazon.awssdk.services.dynamodb.model.DescribeStreamRequest) operation. The
return type is a custom publisher that can be subscribed to request a stream of response pages. SDK will
internally handle making service calls for you.
When the operation is called, an instance of this class is returned. At this point, no service calls are made yet
and so there is no guarantee that the request is valid. If there are errors in your request, you will see the
failures only after you start streaming the data. The subscribe method should be called as a request to start
streaming data. For more info, see
Publisher.subscribe(org.reactivestreams.Subscriber). Each call to the subscribe
method will result in a new Subscription i.e., a new contract to stream data from the
starting request.
The following are few ways to use the response class:
1) Using the forEach helper method
software.amazon.awssdk.services.dynamodbstreams.paginators.DescribeStreamPublisher publisher = client.describeStreamPaginator(request);
CompletableFuture<Void> future = publisher.forEach(res -> { // Do something with the response });
future.get();
2) Using a custom subscriber
software.amazon.awssdk.services.dynamodbstreams.paginators.DescribeStreamPublisher publisher = client.describeStreamPaginator(request);
publisher.subscribe(new Subscriber<software.amazon.awssdk.services.dynamodb.model.DescribeStreamResponse>() {
public void onSubscribe(org.reactivestreams.Subscriber subscription) { //... };
public void onNext(software.amazon.awssdk.services.dynamodb.model.DescribeStreamResponse response) { //... };
});
As the response is a publisher, it can work well with third party reactive streams implementations like RxJava2.
Note: If you prefer to have control on service calls, use the
describeStream(software.amazon.awssdk.services.dynamodb.model.DescribeStreamRequest) operation.

describeStreamRequest - A Consumer that will call methods on DescribeStreamInput.Builder to create a request.
Represents the input of a DescribeStream operation.default CompletableFuture<GetRecordsResponse> getRecords(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.
getRecordsRequest - Represents the input of a GetRecords operation.GetShardIterator action.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.

default CompletableFuture<GetShardIteratorResponse> getShardIterator(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.
