GetShardIteratorRequest

The sequence number of a stream record in the shard from which to start reading.

The identifier of the shard. The iterator will be returned for this shard ID.

Determines how the shard iterator is used to start reading stream records from the shard:

The Amazon Resource Name (ARN) for the stream.

The timestamp of the stream record from which to start reading. Used with shard iterator type AT_TIMESTAMP. A timestamp is the Unix epoch date with precision in milliseconds. For example, 1791316726.480. The iterator points to the first stream record whose ApproximateCreationDateTime is at or after the specified timestamp. If no record with that exact timestamp exists, the iterator points to the next (later) record. If the timestamp is older than the current trim horizon, the iterator points to the oldest untrimmed stream record (TRIM_HORIZON). If the timestamp is in the future, the request returns a ValidationException.
