## Source (`component` YAML, verbatim)

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