Subject [jira] [Commented] (GEODE-1209) Support/Propagating eviction and expiration operation with AsycEventQueue.
Date Wed, 13 Apr 2016 19:09:25 GMT


Robert Geiger commented on GEODE-1209:

In the case of an eviction or expiration that is intended only to conserve memory space by
removing least used keys it does not seem to be required to support propagation of these events
to the underlying cache store. In the case where data has a time to live that applies globally
(both in memory and in persistent storage), and that TTL expires, it would seem it is desirable
to support such a method for the expiration event to be propagated so that the item can be
removed from the cache stores.

> The AsyncEventQueue works as a write-behind cache event handler to synchronize region
updates with other source...Currently it does not support distribution of eviction or expiration
operation....This makes the external source to be out of sync with data that has been removed/invalidated
through eviction and expiration.
> This ticket is to add/support eviction and expiration operation with AsyncEventQueue,
so that all the operations are propagated to AsyncEventQueueListener and the usage of those
events are left to underlying implementation/applications(like WAN, Lucene, plug-able storage,
