             Summary: Aggregate recommender blows up if row count estimate is 
too high
                 Key: CALCITE-760
                 URL: https://issues.apache.org/jira/browse/CALCITE-760
             Project: Calcite
          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.
