Subject [jira] [Resolved] (JCR-3450) Reduce memory usage of SharedFieldCache.ValueIndex
Date Mon, 22 Oct 2012 11:56:12 GMT

     [ https://issues.apache.org/jira/browse/JCR-3450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex Parvulescu resolved JCR-3450.
----------------------------------

       Resolution: Fixed
    Fix Version/s: 2.6
         Assignee: Alex Parvulescu

The patch verifies that the use of ComparableArrays is needed, if not it falls back on simple
Comparable values. This circumvents the creation of unneeded arrays so it should fix the extra
memory consumption problem introduced by JCR-2906 in the cases where there are only simple
values.

Thanks Marcel for the offline feedback.

fixed with rev 1400843.

> JCR-2906 introduced support for order by on multi-valued properties. It looks like this
increased memory usage for the SharedFieldCache.ValueIndex because of the additional arrays
that are used even if there is only a single value for a given property on a node.
