niebayes opened a new issue, #19882: URL: https://github.com/apache/datafusion/issues/19882
We have leaf Scan operator that reads data from in-memory and on-disk sources. Data from in-memory sources are not ordered, while data from on-disk sources are ordered since the flush operation enforces ordering. Data from a source would be wired to different partitions of the Scan operator. I'm wondering if it's reasonable to add partition-level output ordering in the PlanProperties for optimizing scenarios with plans like Scan -> Sort. -- This is an automated message from the Apache Git Service.
