hey @Rajib Rajib Mandalโ , this is very easy, i have done this multiple times, you can segregate data using your IAM role that is attached to the cluster, it is known as an Instance profile, you can only give the dev data access to dev role and the so on for other 2 test and prod cluster.and it will work like as you want
