Darrel Schneider updated GEODE-3845:
------------------------------------
Labels: GeodeOperationAPI (was: )
> Distributed destroy on eviction
> -------------------------------
>
> Key: GEODE-3845
> URL: https://issues.apache.org/jira/browse/GEODE-3845
> Project: Geode
> Issue Type: New Feature
> Components: docs, eviction
> Reporter: Masaki Yamakawa
> Priority: Major
> Labels: GeodeOperationAPI
>
> I use entry-idle-time and eviction together in a partition region that holds
> one redundant copy.
> Details of setting are as follows:
> {code:xml}
> <region name="Data" refid="PARTITION">
> <region-attributes>
> <entry-idle-time>
> <expiration-attributes timeout="60" action="destroy" />
> </entry-idle-time>
> <partition-attributes redundant-copies="1" />
> <eviction-attributes>
> <lru-entry-count maximum="10" action="local-destroy" />
> </eviction-attributes>
> </region-attributes>
> </region>
> {code}
> In this setting, the data held by the cache server is different. Then,
> inconsistent results are returned depending on the server to be connected.
> Eviction of the partition region can only select local-destroy or
> overflow-to-disk. On the other hand, it is written that the expire chapter of
> the document can not use local-destroy, local-invalidate in the partition
> region. Likewise, I think that data inconsistency will occur even with the
> settings like this time.
> Below is the test code:
> [https://github.com/masaki-yamakawa/geode/blob/bug-partition-local-destroy/geode-core/src/test/java/org/apache/geode/internal/cache/partitioned/BugExpireAndEvictionDUnitTest.java]
> I think that it is necessary to add a check at the time of region creation or
> write it in the document.
>
> **
> Problem: currently eviction-action must be either 'local-destroy' or
> 'overflow-to-disk'
> ex: <expiration-attributes timeout="60" action="local-destroy" />
> Solution: This story is to add the additional option "distributed-destroy" as
> an action setting for any eviction type.
> This will enable a local destroy action to be distributed across the cluster
> (currently this does not exist)
>
> Acceptance: can set this on region configuration via cache.xml, API or gfsh
> gfsh help and docs have been updated
>
