Serverless Tip #16: DynamoDB streams unlock many useful patterns

When a DynamoDB stream on a table is enabled, it will capture a time-ordered sequence of item-level modifications to your table. Consuming applications can access stream records in near real-time, allowing for use cases and patterns, such as:

• Triggering events when specific items are updated.
• Updating an aggregated table when items are updated.
• Archiving data for audit and analytics purposes.
• Implementing the transactional outbox pattern.
• Replicating data to another database.
• Aiding in data migration.
