We may want to consider following Spark's approach here, since we are already implementing other methods such as `required_child_distribution` based on Spark. For sorting, Spark has: ```scala /** Specifies how data is ordered in each partition. */ def outputOrdering: Seq[SortOrder] /** Specifies sort order for each partition requirements on the input data for this operator. */ def requiredChildOrdering: Seq[Seq[SortOrder]] ``` -- This is an automated message from the Apache Git Service.
