   @siddharthteotia if we have 5 tables on different tenant, all of them need to join with the same dimension table. If we always colocate them using the same tenant, we need to have 5 copies of the dimension table stored in the deep store. If we use a separate tenant for the dimension table, we only need to store one copy. Each server can be configured with multiple tenants, so that both the fact table and dimension table are still colocated.
   This is out of the scope of this PR, just how to manage the cluster.
