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.
