Is it possible to have triggers (like SQL triggers) in DynamoDB?

Question

I would like to have an action triggered every time an item is created or updated on a DynamoDB. I have been going through the doc, but cannot find anything like this. Is it possible?

Thanks.

Answer 1

This is not possible. DynamoDB doesn't let you run any code server-side. The only thing which might count as server-side actions as part of an update are conditional updates, but those can't trigger changes to other items.

Answer 2

The new update supports triggers.
