Values.GetShardIteratorInputSourceRepresents the input of a GetShardIterator operation.
type nonrec t = {streamArn : StreamArn.t;The Amazon Resource Name (ARN) for the stream.
*)shardId : ShardId.t;The identifier of the shard. The iterator will be returned for this shard ID.
*)shardIteratorType : ShardIteratorType.t;Determines how the shard iterator is used to start reading stream records from the shard: AT_SEQUENCE_NUMBER - Start reading exactly from the position denoted by a specific sequence number. AFTER_SEQUENCE_NUMBER - Start reading right after the position denoted by a specific sequence number. TRIM_HORIZON - Start reading at the last (untrimmed) stream record, which is the oldest record in the shard. 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. LATEST - Start reading just after the most recent stream record in the shard, so that you always read the most recent data in the shard.
*)sequenceNumber : SequenceNumber.t option;The sequence number of a stream record in the shard from which to start reading.
