[GitHub] [incubator-pinot] sajjad-moradi opened a new pull request #7053: Fix bug for AggregateMetrics rule in Recommendation Engine
sajjad-moradi opened a new pull request #7053:
URL: https://github.com/apache/incubator-pinot/pull/7053
## Description
Currently AggregateMetric rule looks at selection columns and all of them have to be metric and inside a SUM function. It misses the fact that for group-by queries, groupby columns appear in selection with no function and that's a valid case for which AggergateMetrics can be turned on. This PR checks that scenario and acts accordingly.
## Testing Done
- unit test
- integration test

This won't work if the group by expression is a transform function?
