👋 Hi -- while testing `datafusion-distributed `against the new `datafusion` release branch, we found this change breaks queries with uncorrelated subqueries when there's a network boundary between the `ScalarSubqueryExec` and the node containing the `ScalarSubqueryExpr`, because the two communicate via a shared `slot`, and that shared state doesn't survive between the workers. I left a small explanation here: https://github.com/datafusion-contrib/datafusion-distributed/issues/460. We'll work on a proper fix on our end to make distributed execution work with this new node, but in the meantime, would it be feasible to put this new planning behavior behind a session property? -- This is an automated message from the Apache Git Service.
