How to use AWS AppSync in one account access DynamoDB in another account?

Question

I am a beginner of AWS service AppSync and DynamoDB. I want to ask whether it is possible to use AWS AppSync in one account access DynamoDB in another account? I follow this tutorial: AppSync Tutorial, but when I choose the data source, I don't know how to choose the DynamoDB in my other AWS account.

Could anyone give me some suggestions about the most simple method to implement cross-account access with AppSync and DynamoDB? Thanks in advance!

Answer 1

I think the best way is: replicate a DynamoDB in account A from account B by using DynamoDB Stream and Lambda, and then we can use AppSync in account A to access DynamoDB in account A.
