While pushing the index changes<br>is done in sync with the transaction commit (tx sync), the backend is<br>JGroups and returns right after it has sent the message to the master<br>node without waiting for the index ack.<br>This is a good thing as it scales much better but has the nice<br>side effect of returning incorrect query results right after a change<br>set is applied (indexing window + index propagation).<br><br>My recommendation is to make sure Infinispan Query removes entities<br>found by the query engine but not present in the grid like we do in<br>Hibernate Search for the ORM case. Note that this does not solve the<br>case were you add a new entity and expect to query it *right after the<br>commit*. There is a similar issue around entity changes. If CapeDwarf<br>can live with it it will be better off.<br><br>An alternative solution would be to create a JGroups backend that waits<br>for an execution ACK before giving back the had to the client but that<br>will have scalability problems.<br><br>Emmanuel<br><br>On Tue 2013-04-09 23:41, Ales Justin wrote:<br><br>Chasing down today's NPE: <a href="http://pastie.org/7382216">http://pastie.org/7382216</a><br><br>I've added this test:<br>* <a href="https://github.com/capedwarf/capedwarf-blue/commit/d416d5358">https://github.com/capedwarf/capedwarf-blue/commit/d416d5358</a><br><br>The test fails. ;-)<br><br>deleteAndQueryInA(org.jboss.test.capedwarf.cluster.test.QueryTest): Should<br>not be here: null<br><br>This is the "null" that is the cause of top NPE.<br><br>-Ales<br><br><br>_______________________________________________<br>infinispan-dev mailing list<br><a href="mailto:infinispan-dev@lists.jboss.org">infinispan-dev@lists.jboss.org</a><br>https://lists.jboss.org/mailman/listinfo/infinispan-dev<br><br><br>_______________________________________________<br>infinispan-dev mailing list<br>infinispan-dev@lists.jboss.org<br>https://lists.jboss.org/mailman/listinfo/infinispan-dev<br><br><br><br>_______________________________________________<br>infinispan-dev mailing list<br>infinispan-dev@lists.jboss.org<br>https://lists.jboss.org/mailman/listinfo/infinispan-dev<br></blockquote>_______________________________________________<br>infinispan-dev mailing list<br><a href="mailto:infinispan-dev@lists.jboss.org">infinispan-dev@lists.jboss.org</a><br>https://lists.jboss.org/mailman/listinfo/infinispan-dev<br></blockquote></div><br></body></html>
