Subject [jira] [Commented] (HIVE-5182) log more stuff via PerfLogger
Date Thu, 05 Sep 2013 21:25:51 GMT


Ashutosh Chauhan commented on HIVE-5182:

I will suggest to add it inside serialize/deserializeObject as well, since we have caches
around these objects. So, if our code is working correctly, this should not be called more
than once per process. Further, if we do see them getting printed multiple times, we know
we got something to fix.

> PerfLogger output is useful in understanding perf. There are large gaps in it, however,
and it's not clear what is going on during these. Some sections are large and have no breakdown.
It would be nice to add more stuff. At this point I'm not certain where exactly, whoever makes
the patch (me?) will just need to look at the above gaps and fill them in.
