1.20 was the last non-bug-fix release before Flink 2.0, you can found all main upgrade features in this [release note](https://nightlies.apache.org/flink/flink-docs-release-1.20/release-notes/flink-1.20/). I think the most important feature related to Celeborn is we expose some interface to support Flink hybrid shuffle integration with Celeborn([FLIP-459](https://cwiki.apache.org/confluence/display/FLINK/FLIP-459%3A+Support+Flink+hybrid+shuffle+integration+with+Apache+Celeborn)). This(supporting hybrid shuffle in Celeborn side) is also a follow-up stuff to this PR. incompatible changes in 1.20: - 1.20 use enum `CompressionCodec` instead of `String` to construct `BufferDecompressor` and `BufferCompressor`. - 1.20 introduce a new method(`notifyPartitionRecoveryStarted`) to `JobShuffleContext` in a non-compatible way. I've already done the adaptation in this PR. Closes #2662 from reswqa/support-120. Authored-by: Weijie Guo <reswqa@163.com> Signed-off-by: Shuang <lvshuang.xjs@alibaba-inc.com> |
