Github user ggevay commented on the issue: https://github.com/apache/flink/pull/3511 I'm not exactly sure how to do `FixedLengthRecordSorter`. @greghogan , could you please clarify what you meant in the following? > Rather than extending NormalizedKeySorter, we could pull the compare and swap functions out of > MemorySegment into an interface with a default implementation moved from NormalizedKeySorter > and FixedLengthRecordSorter. There is overlap in that the normalizedKeyFullyDetermines case of > NormalizedKeySorter results in the same operations as in FixedLengthRecordSorter. Do you mean that the generated code would implement this interface? What would be the relation between the non-generated `NormalizedKeySorter` class and this interface? Would this change introduce more virtual calls?
