I have Azure Cosmos DB account which has been provisioned with "Provisioned throughput" capacity mode. Currently we have less usage on the resources hence trying to reduce the RU’s database. I go to My Azure Cosmos DB account -> Data Explorer -> Select the instance -> Scale & Setting. I tried to reduced the RU’s to lower range but somehow "Save" option is disable.
I have "owner" privilege’s for entire subscription however Save option is disabled. I am trying to lower the RU from 8000 to 800 however i am unable to save it. Is this because of RBAC issue or is it because of the fact that i created my account beginning in such a way that i wont be able to scale throughput? Please assist.
>Solution :
You need to have at least 1000 RU/s provisioned for autoscale. It was 4000 RU/s until just recently.
The entry point for autoscale maximum throughput Tmax starts at 1000 RU/s, which scales between 100 – 1000 RU/s. You can set Tmax in increments of 1000 RU/s and change the value at any time.
