We have a multi tenants environment and each client occupies x number of hbase regions. We currently have about 500 regions per region server and I understand the guideline is less than 200. So we need to reduce the region counts. Increasing region file size is no more an option because we are already at 5G and I don’t want to go higher.
Due to our unique use cases, all clients are running for a few hours in a day, then being quiet for the rest of time. So I am thinking whether it is a good idea to disable all quiet tables and only enable them when they are ready to run. Does anyone have experience on that? One thing I worry about is the Balancer. I am pretty sure the balancer will be confused when regions come and go. And I cannot afford not to have it running in case of region server crashes and come back. So doesn’t anyone have good ideas how to handle it? I already doing compact myself so that is not an issue. Another related question, if a region is enabled but not active read/write, how much resources it takes in terms of region server? Thanks!
