I am using Azure Cache for Redis Enterprise (E1) Tier for my application. Due to limit of costs, I would like to use the same instance for two environments: test and staging. How can I create separate db? Is there any limit of the number of dbs because of the tier? I was trying to find in the Microsoft documentation, but I couldn’t.

When I try the command INFO keyspace I got this output:
db0:keys=1,expires=0,avg_ttl=0
When I try to SELECT 1 add new KEY I got this error:
Redis Client Error [ErrorReply: ERR DB index is out of range]

Could you please help me with this issue?

Thank you in advance!
