> 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;
