DynamoDB Streams and Global Tables
Learn how to react to data changes in real time with DynamoDB Streams and build multi-region, low-latency applications using Global Tables.
Reacting to Changes
Sometimes you need to know the moment data changes — to update a cache, send a notification, or sync another system.
DynamoDB Streams capture an ordered log of every item-level change in a table.
What a Stream Records
Each stream record describes an INSERT, MODIFY, or REMOVE. You choose what data the record carries via the stream view type:
- KEYS_ONLY
- NEW_IMAGE
- OLD_IMAGE
- NEW_AND_OLD_IMAGES
