Subject [jira] [Updated] (GEODE-3293) Option to invalidate state data after a cluster crash
Date Tue, 25 Jul 2017 15:24:00 GMT

     [ https://issues.apache.org/jira/browse/GEODE-3293?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Fred Krone updated GEODE-3293:
------------------------------
    Description: 
This story is an epic to wrap mitigating to stale cache data.

When GemFire is used is a fast moving data scenario every second it is down its data becomes
more stale vs a system of record like a backing DB.  When the cluster is recovered its data
will essentially be an aging snapshot.  In scenarios where data accuracy is essential (always?)
it would be nice to have an option to invalidate stale data before allowing reads.
