Backports #18696 to Flink 1.20 and 2.2. `SortKeySerializer` wrote FIXED and BINARY sort key fields from the buffer's full backing array. A binary key truncated by the sort order was therefore deserialized as the original untruncated value. Keys learned by range distribution then did not match incoming keys, and records fell back to round robin. The serializer now writes only the buffer's remaining bytes through `ByteBuffers.toByteArray`. With this change, the affected files in Flink 1.20 and 2.2 are identical to their Flink 2.3 versions. --- **AI Disclosure** - Model: Claude Opus 5.5 - Platform/Tool: Claude Code - Human Oversight: [unknown - human to fill in] - Prompt Summary: Backport the #18696 binary sort key serialization fix from Flink 2.3 to Flink 1.20 and 2.2; the code changes are copied from the merged Flink 2.3 change. -- This is an automated message from the Apache Git Service.
