Marco Gaido created SPARK-26018:
-----------------------------------

             Summary: Support Scalar subqueries in predicate push down to datasources
                 Key: SPARK-26018
                 URL: https://issues.apache.org/jira/browse/SPARK-26018
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Marco Gaido


As of now, existing datasources are not using filters containing scalar subqueries for their predicate pushdown. This ticket aims to support that as a result of the discussion in https://github.com/apache/spark/pull/22518.
