> Over the weekend we ran into an issue of running normalizer on a table with ~400k regions and we noticed the master was bottlenecked on merge dispatcher code that runs on a single threaded thread-pool that was meant for all master table operations (opcode: MASTER_TABLE_OPERATIONS). Having a dedicated thread-pool helped us dispatch merges at a faster rate.
