I have a DynamoDB global table with replicas in two regions, and I want to enable Kinesis Data Streaming. For any write to either table I want only one Kinesis event. What is the suggested approach to do this?
My question is:
Should I enable Kinesis Data Streams on one region's table only, or on all the regions? If the latter, should they all point to the same Kinesis stream?
My expectation is that I don't need to enable Kinesis Data streams on multiple DynamoDB replicas, but only on one, as all records will be synchronized to that table.
No, you should only enable it for a single region, as if you configure it on multiple regions you will have N number of events, where N is the number of replicas.
