You now can use AWS CloudTrail to log Amazon DynamoDB Streams data-plane API activity

You now can use AWS CloudTrail to log Amazon DynamoDB Streams data-plane APIs—GetRecords and GetShardIterator—to monitor and investigate item-level changes in your DynamoDB tables. Previously, you could use CloudTrail to log DynamoDB Streams control-plane activity (and not data-plane activity) on your DynamoDB tables.
