> 2\. Disable comet coalesce when ANSI mode is enabled. This is because coalesce in comet throws an exception while spark suppresses it To clarify this a bit more, Spark performs lazy evaluation on the inputs to `coalesce` and will stop evaluating as soon as it finds the first non-null input. Comet (and DataFusion) currently evaluate all of the inputs. This is why we see an error in Comet but not in Spark. -- This is an automated message from the Apache Git Service.
