DynamoDB tables impact of DAX is created with permissions to access all tables

Question

I'm curious about the implications of allowing a DAX cluster to access all tables. If I grant DAX this access, will all tables be affected? I understand that for caching, DAX needs to interact with all of DynamoDB, which might suggest a potential degradation in table performance. Could you provide more details on this?

Thanks, Oleksandr

Answer

No there will be no table degradation. DAX will have to interact with all tables yes, but the alternative is your client directly interacts with all tables. DynamoDB will still maintain its performance so long as you follow DynamoDB best practices.
