Darrel Schneider commented on GEODE-3845:
-----------------------------------------

If both are configured the expiration action is still distributed. It does not 
become local.
A decision was made to allow eviction local-destroy on a partitioned region 
even though it can cause the primary and secondary to not be consistent.
At this time I think the main action item for this ticket is to document that 
configuring evict destroy can lead to inconsistencies on a partitioned region 
and describe under what conditions these inconsistencies will arise. We should 
consider making changes to how these partitioned regions are implemented that 
would cause them to be consistent when evict destroy is configured.


> local-destroy setting of eviction breaks the consistency of the partition 
> region

> 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.
