stack commented on HBASE-10010:
-------------------------------
Patch looks good to me. Add TODO for compressed writing case if you want and
we can come back and do that later. Suggest that
'Arrays.equals(key.getEncodedRegionName(), HLog.DUMMY_REGION)' be put inside a
static method in /HLogUtil.java since it is repeated in a few places.
> eliminate the put latency spike on the new log file beginning

> In deed, the original finding came from fb, see HBASE-6813 for detailed
> discussion.
> Through this improvement doesn't expect obvious gain on 95th or 99th latency,
> it still could make the response time more stable to me.
