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. -- This message is automatically generated by JIRA.
