> 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
> Priority: Major
> Fix For: v1.16
>
>
> 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.
