> Issue Type: Bug
> Reporter: Julian Hyde
> Assignee: Julian Hyde

> If you run the aggregate recommendation algorithm with a value of
> rowCountEstimate that is wrong and large, the algorithm runs for a long time
> and eventually fails with "OutOfMemoryError: GC overhead limit exceeded".
> I have added LatticeTest.testLatticeWithBadRowCountEstimate as a test case.
