Subject [jira] [Created] (HBASE-5776) HTableMultiplexer
Date Thu, 12 Apr 2012 21:43:19 GMT

                 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.
