Barrett Oglesby commented on GEODE-8926:
----------------------------------------
I attached a sequence diagram showing the the interleaved behavior that causes
the issue.
> CQ events can be missed while executing with initial results simultaneously
> with transactions

> Key: GEODE-8926
> URL: https://issues.apache.org/jira/browse/GEODE-8926
> Project: Geode
> Issue Type: Bug
> Components: cq
> Reporter: Barrett Oglesby
> Priority: Major
> Attachments: cq_with_transaction_behavior.png
>
>
> In this case, the event is not in either the initial results or received in
> the CqListener.
> A test that shows the behavior is:
> - 2 servers with:
> - a root PR
> - a colocated child PR
> In a client, asynchronously:
> - start a transaction that:
> - does N puts into the root PR
> - does 1 put into the child PR
> - commit the transaction
> In the client:
> create N CQs with initial results with: 'select * from /childPR'
> When the test succeeds, all the CQs either get the 1 event in their initial
> results or in their CqListener.
> When the test fails, one or more CQs don't see the event either way.
