branch-4.1: [fix](be) Use serialized hash keys for complex types #66777 - #66828
Merged
Conversation
### What problem does this PR solve? Problem Summary: Multi-column hash keys could incorrectly classify fixed-width complex types such as `STRUCT` as fixed keys. Because `ColumnStruct` stores its fields in separate child columns, it cannot be packed from a contiguous raw buffer. This change routes multi-column keys containing complex types through the serialized-key path, fixing `GROUP BY` and distinct aggregate failures involving fixed-width `STRUCT` columns. ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test. Explain why: - [ ] This is a refactor/code format and no logic has been changed. - [ ] Previous test can cover this change. - [ ] No code files have been changed. - [ ] Other reason <!-- Add your reason? --> - Behavior changed: - [ ] No. - [ ] Yes. <!-- Explain the behavior change --> - Does this need documentation? - [ ] No. - [ ] Yes. <!-- Add document PR link here. eg: apache/doris-website#1214 --> ### Check List (For Reviewer who merge this PR) - [ ] Confirm the release note - [ ] Confirm test cases - [ ] Confirm document - [ ] Add branch pick label <!-- Add branch pick label that this PR should merge into -->
