Cross-Region DynamoDB Access

Question

I haven't been able to find a clear answer on this from the documentation.

Is is discouraged to access DynamoDB from outside the region it is hosted in? For example, I want to do a lot of writes to a DynamoDB table in us-west-2 , from a cluster in us-east-1 (or even ap-southeast-1 ). My writes are batched and non-real-time, so I don't care so much about a small increase in latency.

Note that I am not asking about cross-region replication.

Answer 1

DynamoDB is a hosted solution but that doesn't mean you need to be inside AWS to use it.

There are cases, especially for storing user information for clients making queries against DynamoDB - outside of "AWS region".

So to answer your question - best performance will be achieved when you mitigate the geo barrier, but you can work with any endpoint you'd like from anywhere in the world.
