Tianying Chang updated HBASE-8836:
----------------------------------
Attachment: hbase-8836.patch
This is the first draft, with some unnecessary LOG.info and so on still there.
I want to upload this first version to get some feedback before I make
refinement of the code. I also have Performance Evaluation number from running
on a real cluster, which meet my expectation for improving the write
throughput. I will upload the data later also.
> Separate reader and writer thread pool in RegionServer, so that write
> throughput will not be impacted when the read load is very high

> We found that when the read load on a specific RS is high, the write
> throughput also get impacted dramatically, and even cause write data loss
> sometimes. We want to prioritize the write by putting them in a separate
> queue from the read request, so that slower read will not make fast write
> wait nu-necessarily long.
