>
> During batch loading of partition the write notification logs are added for
> each partition added. This is causing delay in execution as the call to HMS
> is done for each partition. This can be optimised by adding a new API in HMS
> to send a batch of partition and then this batch can be added together to the
> backend database. Once we have a batch of notification log, at HMS side, code
> can be optimised to add the logs using single call to backend RDBMS.
