We're looking at DynamoDB disaster recovery and resiliency, the AWS docs mention the concept of a Local Region which I can't find any other mentions of in their documentation portal.
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/disaster-recovery-resiliency.html
The only other mention I could find is here:
https://wa.aws.amazon.com/wat.concept.local-region.en.html
Can anyone point out what these are and how to use them? and some documentation links?
