[infinispan-issues] [JBoss JIRA] (ISPN-863) Eviction based on JVM memory utilization

[Marc Bridner (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12761657#comment-12761657 ] 

Marc Bridner commented on ISPN-863:
-----------------------------------

The very naive implementation of freeMemory/totalMemory (configurable as both a percentage and fixed value) would still be very useful in the cases where Infinispan is the only thing inside the JVM, an embedded or standalone Infinispan that is accessed remotely by hotrod for example. It needs a big "USE WITH CARE" warning, but for some usecases it would be a lot better than the fixed size eviction that is currently in use.

> Allow user to specify percentage threshold upon which eviction will kick in and begin evicting entries based on the specified strategy. This would allow user to create a cache that will attempt to keep as many entries in memory as possible without having to specify maxEntries.
