[GitHub] [arrow-datafusion] liukun4515 commented on pull request #4725: Support non-tuple expression for in-subquery to join

URL: https://github.com/apache/arrow-datafusion/pull/4725#issuecomment-1364999536

   why not implement this in the rule `decorrelate_where_in.rs`?
   
   The two rule of `decorrelate_where_in.rs` and `subquery_filter_to_join.rs` implement the same function, and convert the `in query` to Join. Maybe we can reduce the duplicate code and reduce the rule. cc @jackwener
