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

             Summary: NonBlockingStore.batch(...) processes writes as removals
                 Key: ISPN-12097
                 URL: https://issues.redhat.com/browse/ISPN-12097
             Project: Infinispan
          Issue Type: Bug
          Components: Core, Loaders and Stores
    Affects Versions: 11.0.1.Final
            Reporter: Paul Ferraro
         Attachments: Test.java

There seems to be something amiss with the new NonBlockingStore changes.  When a transactional invalidation cache is used with a shared cache store, I've observed the removePublisher of the NonBlockStore.batch(...) receive subscriptions for entries that should have been published to the writePublisher.

See the attached test to reproduce the issue, which executes two simple cache operations against a transactional vs non-transactional cache using a shared write-through store.  The transactional version fails due to unexpected removals triggered by the batch(...) method (which, in the case of the JDBC store delegates to the deleteBatch(...) and bulkUpdate(...) methods.  TRACE logging indicates that entries are unexpectedly published to the removePublisher of batch(...) when transactions are enabled causing entries to be removed unexpectedly from the store (as the result of a Cache.put(...)).  When tx are disabled, the batch(...) method is, of course, not in play, and everything works correctly via the individual write/delete methods.
