> Instead of creating a fixed size connection pool for TxnHandler#MutexAPI, the
> pool can be assigned to a more dynamic size pool due to:
> * TxnHandler#MutexAPI is primarily designed to provide coarse-grained mutex
> support to maintenance tasks running inside the Metastore, these tasks are
> not user faced;
> * A fixed size connection pool as same as the pool used in ObjectStore is a
> waste for other non leaders in the warehouse;
