Subject [jira] [Updated] (HBASE-16224) Reduce the number of RPCs for the large PUTs
Date Sat, 06 Aug 2016 08:30:20 GMT

ChiaPing Tsai updated HBASE-16224:
----------------------------------
    Description: 
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
