Subject [jira] [Commented] (ACCUMULO-1409) Make MiniAccumuloCluster support native maps
Date Thu, 16 May 2013 17:13:19 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13659725#comment-13659725

David Medinets commented on ACCUMULO-1409:
------------------------------------------

Will this add another bit of complexity? The single node accumulo instance
is intended to what amount of entries? At what size does the having the
native map truly affect performance? And to what degree? One billion
entries ... Fifty Billion entries?

> 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.
