blocking write. But for master branch, the > result shows the async write has better latency than the blocking client. > Take a look about the code, I thought the difference is the BufferedMutator. > For master branch, HTable don't have a write buffer and all write request > will be flushed directly. And user can use BufferedMutator when user want to > perform client-side buffering of writes. For the performance issue > (autoFlush=True), I thought we can use rpc caller directly in HTable's put > method.
