> Putting this planning behavior behind a session property will be non-trivial, because various parts of the planner code have been simplified to assume that uncorrelated scalar subqueries will not be rewritten into joins (partly as part of this PR; also in https://github.com/apache/datafusion/pull/22316, maybe elsewhere). I see 🤔 maybe I can give it a try and see how ugly it gets > How difficult will it be for datafusion-distributed to adapt to this change, do you think? I think it would require a significant amount of work and thought -- we already have similar cross-worker shared-state work pending in order to make dynamic filtering work in the project, so maybe we will pick it up soon. Was just wondering if it would be simple enough to put this behind a flag to unblock the upgrade on our side. Also wondering if ballista bumped into the same issue when they tested the new release branch? cc @milenkovicm -- This is an automated message from the Apache Git Service.
