Hello, After updating to Datafusion 21.0.0 I have noticed that codebase has deadlocks anytime that the `optimize` method is called. I have tracked down the location where the deadlock is happening to [1]. The call to `plan.hash( &mut hasher);` never returns. Does anyone have any ideas on what might be going on here?
Thanks, Jeremy Dyer [1] - https://github.com/apache/arrow-datafusion/blob/main/datafusion/optimizer/src/plan_signature.rs#L64
