Research direction
Start by reviewing the aws-record API for put operations and DynamoDB conditional writes. Determine how a caller can ensure the item has not changed since it was read, then document or implement a supported approach and verify it against the requested read-modify-save scenario.

Description
Hi! Is there any way to do a conditional put request? The case when I get some data, change it by some operations and I want to save it back only if data in DynamoDB still the same when I get it.
Maybe you could give me an advice how to implement it with a few changes.
