>            Priority: Minor
>              Labels: performance
>   Original Estimate: 96h
>  Remaining Estimate: 96h

> When doing bulkload , some interactive with zookeeper to getting region key range may be cost more time.
> In multithreads enviorment, the duration maybe cost 5 minute or more.
> From the executor log, like 'Reading reply sessionid:0x262fb37f4a07080 , packet:: clientPath:null server ...' contents appear many times.
>  
> It likely to provide new method for bulkload, caching the key range outside
