XiDuo You updated SPARK-37037: ------------------------------ Description: BinaryType use `TypeUtils.compareBinary` to compare two byte array, however it's slow since it compares byte array using unsigned int comparison byte by bye. We can compare them using `Platform.getLong` with unsigned long comparison if they have more than 8 bytes. And here is some histroy about this [https://github.com/apache/spark/pull/6755/files#r32197461 .|https://github.com/apache/spark/pull/6755/files#r32197461] was: BinaryType use `TypeUtils.compareBinary` to compare two byte array, however it's slow since it compares byte array byte by bye.
