------------------------------------
Summary: Pivot: Fix array_agg + distinct scaling issue on gpdb
Key: MADLIB-1361
URL: https://issues.apache.org/jira/browse/MADLIB-1361
Project: Apache MADlib
Issue Type: Bug
Components: Module: Utilities
Reporter: Orhan Kislal
With large datasets, pivot fails because of the array_agg(distinct) query. This
is because array_agg collects the values first and filters the distinct values
later. This causes the array_agg to go out of memory.
