[jira] [Created] (GEODE-3845) local-destroy setting of eviction breaks the consistency of the partition region

--------------------------------------

             Summary: local-destroy setting of eviction breaks the consistency of the partition region
                 Key: GEODE-3845
                 URL: https://issues.apache.org/jira/browse/GEODE-3845
             Project: Geode
          Issue Type: Bug
          Components: eviction
            Reporter: Masaki Yamakawa


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 local-invalidate. 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.
