It is also related to the CacheStore API refactoring scheduled for 6.0 [1].</div><div><br></div><div>The problem: </div><div>When configuring an XA cache with a cache store it is possible for the cache store to end up out of sync with in-memory data. In order to overcome that we would need cache store enhancements.</div><div><br></div><div>Whilst this is definitely a limitation and a nice to have feature not sure that 6.0 is the time and place to start this enhancement. Why? </div><div>There doesn't seem to be any explicit demand from the community/JDG for this feature at the moment, so other features should take priority. There's also a potential workaround for this: don't configure a cache store but the user to manage the XA write in the store directly.</div><div>Wdyt?</div><div><br></div><div>I've also updated the documentation to clearly state that inconsistencies are possible[2].</div><div><br></div><div>Cheers,</div><div>Mircea</div><div><br></div><div>[1] <a href="https://community.jboss.org/wiki/CacheLoaderAndCacheStoreSPIRedesign">https://community.jboss.org/wiki/CacheLoaderAndCacheStoreSPIRedesign</a> </div><div>[2] <a href="https://docs.jboss.org/author/display/ISPN/CacheLoaders#CacheLoaders-CacheLoadersandtransactionalcaches">https://docs.jboss.org/author/display/ISPN/CacheLoaders#CacheLoaders-CacheLoadersandtransactionalcaches</a></div><div><br></div></body></html>
