// 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 (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide//Streams.html).
//
// Note that this document is intended for use with the following DynamoDB
// documentation:

//    Amazon DynamoDB Developer Guide (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/)
//
//    Amazon DynamoDB API Reference (http://docs.aws.amazon.com/amazondynamodb/latest/APIReference/)
//
//   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.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
