> This patch is proposed to reduce the number of RPC for the large PUTs
> The number and data size of write thread(SingleServerRequestRunnable) is a
> result of three main factors：
> 1) The flush size taken by BufferedMutatorImpl#backgroundFlushCommits
> 2) The limit of task number
> 3) ClientBackoffPolicy
> A lot of requests created with less MUTATIONs is a result of two reason:
> 1) many regions of target table are in different server.
> 2) flush size in step one is summed by “all” server rather than “individual”
> server
> This patch removes the limit of flush size in step one and add maximum size
> to submit for each server in the AsyncProcess
