How Python Data Engineers Use Amazon DynamoDB

Python data engineers use `boto3`'s DynamoDB resource to store pipeline state, idempotency tokens, and metadata that needs sub-millisecond lookup by key. DynamoDB Streams connected to Lambda functions enable event-driven pipeline triggers — each new record insert automatically kicks off downstream processing without polling.
