testNQueriesWaitingForSameSegmentRepeat

public void testNQueriesWaitingForSameSegmentRepeat()
                                             throws ExecutionException,
                                                    InterruptedException

Tests that if N queries are executed at the same time, only one segment request will be sent. The query that arrives second should see that there is a pending segment in the aggregation manager, and should wait for that.

If the test fails, look at segmentCreateViaSqlCount. If it has increased by more than one between before and after, the clients have not managed to share work. If it has not increased, the cache was probably not flushed correctly.

Throws:

ExecutionException

InterruptedException
