HTableMultiplexer
------------------
Key: HBASE-5776
URL: https://issues.apache.org/jira/browse/HBASE-5776
Project: HBase
Issue Type: Improvement
Reporter: Liyin Tang
Assignee: Liyin Tang
There is a known issue in HBase client that single slow/dead region server
could slow down the multiput operations across all the region servers. So the
HBase client will be as slow as the slowest region server in the cluster.
To solve this problem, HTableMultiplexer will separate the multiput submitting
threads with the flush threads, which means the multiput operation will be a
nonblocking operation.
The submitting thread will shard all the puts into different queues based on
its destination region server and return immediately. The flush threads will
flush these puts from each queue to its destination region server.
Currently the HTableMultiplexer only supports the put operation.
