Subject [jira] [Updated] (GEODE-7) Off heap data storage
Date Tue, 30 Jun 2015 21:52:04 GMT

     [ https://issues.apache.org/jira/browse/GEODE-7?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Darrel Schneider updated GEODE-7:
---------------------------------
    Description: 
This is a feature that has been under development for GemFire but was not part of the initial
drop of code for geode.

Geode stores a lot of data in the java heap. With very large heap sizes, this can lead to
performance impacts due to garbage collection time.

Rather than storing data in the java heap, store data in native memory managed by Geode.

Rather than storing data in the java heap, store data in native memory using direct byte buffers
with memory managed by Geode.
