             Summary: LMF performance with GPDB Optimizer
                 Key: MADLIB-1170
                 URL: https://issues.apache.org/jira/browse/MADLIB-1170
             Project: Apache MADlib
          Issue Type: Improvement
          Components: Module: Matrix Factorisation
            Reporter: Orhan Kislal


LMF performance is reduced when the gpdb optimizer is enabled. It seems LMF 
creates a corner case where Orca generates a SubPlan for uncorrelated query in 
the project list. 

Once that problem is solved, we should reevaluate the LMF performance
