@comphead Thanks for reviewing this issue. I believe this change can help reduce scan I/O. Although it may not significantly reduce the end-to-end query time (since the sub-clauses of the UNION can be processed in parallel), it should still bring some benefits. If you're interested in this PR, I'd really appreciate it if you could take a look. -- This is an automated message from the Apache Git Service.
