@j7nhai Hash-based shuffle writer directly serializes the input batches for single partitioning inputs. Sort-based shuffle is implemented as row-format and an extra columnar-to-row / row-to-columnar conversion is introduced in its native implementation. Hence, there's no benefit to using sort-based shuffle for single partition. -- This is an automated message from the Apache Git Service.
