2# Amazon DynamoDB Streams: the item-level change log of a DynamoDB table ("Change data capture for DynamoDB
3# Streams"). That page states a stream is off until you enable it on the table, that records live for 24
4# hours and are then trimmed, that each record appears exactly once and records for a given item appear in
5# the order the item was modified, that encryption at rest encrypts stream data, and that the StreamViewType
6# chosen at enable time cannot be edited afterwards.
