Hi @jaylisde I understand the checksum computation was introduced to resolve the data consistency issue with task retries, and we do lack this support for spark 4.0 in Gluten. But since Gluten's hash-based shuffle handles the data in columnar format, I wonder if it's possible to implement this based on each column buffer? The conversion from columnar to row for the checksum computation looks expensive. -- This is an automated message from the Apache Git Service.
