Subject [jira] [Commented] (ACCUMULO-1409) Make MiniAccumuloCluster support native maps
Date Sat, 20 Jul 2013 02:46:50 GMT


Christopher Tubbs commented on ACCUMULO-1409:

{quote}I suspect enabling them would not help for that case.{quote}

I realize my response is a bit late, but in the interests in conveying the latest information:
At the time that comment was made, I'm sure it was true, but it isn't anymore. Lately, the
only way I can guarantee the integration tests don't time out is if I enable the native maps
with "-P native".

> 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.
