> 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.
