                 Key: SPARK-32943
                 URL: https://issues.apache.org/jira/browse/SPARK-32943

    Affects Versions: 3.1.0
            Reporter: L. C. Hsieh

We observed in our customer payloads that existing optimization of filter pushdown and project combination produces query plan with bad performance in some cases. This is an umbrella for some tasks to improve filter pushdown and project combination.
