GitHub user avamingli added a comment to the discussion: Make UNION Parallel
> Specifically, we can implement a Parallel-oblivious Append approach, where > multiple workers operate independently without sharing state, rather than a > Parallel-aware Append that requires coordination among workers. Done in #1213 > However, for UNION ALL and similar scenarios, the use of Parallel Append is > unsafe. That's another problem and we should consider disabling it in the > future. To be fixed later.
