Yikes. These got mis-filed in my mail. I'm sorry, Steve. > Declare that HSYNC is sufficient and the only one you should look for. If you implement HFLUSH and not HSYNC, you are of no use to applications. retain support for HFLUSH probe, but in the spec only mention it as of historical interest. My only worry with this is that, today, HBase is only running with HFlush and not HSync because of performance reasons. The last wag I remember was in the ballpark of a 30% performance hit for writes if we force hsync instead of hflush. Let me re-read your latest and see if my mind changes. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
