     * Normally buckets are owned by main partition nodes (in POR) and other main partition nodes as well as replica nodes transfer those buckets from owner partition nodes. But
     * their are exceptional cases when we inform other nodes to transfer those buckets from replica nodes. One very obvious use case is when all the nodes left the cluster except
     * one and this last node need to transfer data from the backup available on the same node. This table is used to maintain the bucket ids for which we are not following the
     * rule but exception. Against bucket ids we store backup node address from where other nodes will transfer the bucket.
