§
SequenceNumber?: string | null
[src]The sequence number of a stream record in the shard from which to start reading.
§
ShardIteratorType: ShardIteratorType
[src]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.
