DynamoDB Tables Quota Increase Limits

Question

For any AWS account, there is an [initial DynamoDB table quota of 2,500 tables per AWS Region](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ServiceQuotas.html#limits-tables). One can request a service quota increase using  the [support page](https://aws.amazon.com/support).

Can one assume that requests will always be approved? Can a service design assume an unlimited number of tables? Otherwise, is there a limit to the quota increase for DynamoDB tables?

Answer

One should not assume it will always be approved. Justification must be provided. The table count limit is there as a nudge toward best practices, which usually doesn't involve multiple thousands of tables unless there's been careful consideration of alternative designs first.
