I have a database with enabled option "Provision database throughput". I chose 400 RUs as my throughput. If I have 25 collections in my database, does it mean that they will share 400 RUs between each other or it means that the database has 10,000RUs (400RUs * 25 containers) that will be shared between all containers?
I've read this documentation about provisioned throughput on MSDN, but it still unclear for me. How many throughput capacities I have in my case?
