Frank McQuillan commented on MADLIB-1170:
-----------------------------------------
Is there a way we can track Orca progress on this issue? Do they have a JIRA
somewhere we can follow?
> 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
