Subject [jira] [Created] (HBASE-16224) Reduces the number of RPC for the large PUTs

-------------------------------------

             Summary: Reduces the number of RPC for the large PUTs
                 Key: HBASE-16224
                 URL: https://issues.apache.org/jira/browse/HBASE-16224
             Project: HBase
          Issue Type: Improvement
            Reporter: ChiaPing Tsai
            Priority: Minor


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 threads 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
