Subject [jira] [Commented] (ACCUMULO-1409) Make MiniAccumuloCluster support native maps
Date Fri, 17 May 2013 04:47:16 GMT


Keith Turner commented on ACCUMULO-1409:

bq.  Are we interested in seeing if native maps may help us in our pursuit to speed up the
MAC during the automated integration tests?

I suspect enabling them would not help for that case.  Not much data is written.  I think
a lot of the time is spent in process startup and IPC snafus (i.e. accumulo init tries to
talk to zookeeper before its fully up, it fails and then retries in a bit).

> If a user sets up a single node accumulo instance and uses it for testing, then w/o native
maps the performance will not be as good as it could.  I did some testing of the new GC in
java 7, along the way I noticed a significant difference between the native map and java map.
