Todd Lipcon commented on HBASE-5776:
------------------------------------
Can this be done without adding a new interface? eg can we make the existing
queueing/flushing behavior of HTable use a threadpool?

> Key: HBASE-5776
> URL: https://issues.apache.org/jira/browse/HBASE-5776
> Project: HBase
> Issue Type: Improvement
> Reporter: Liyin Tang
> Assignee: Liyin Tang
> Attachments: D2775.1.patch, D2775.1.patch

>
> 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.
