## What is the purpose of the change When the number of fields exceeds a certain threshold and the compiled method body exceeds 8k, the decode/encode method will not be optimized by JIT, seriously affecting serialization or deserialization performance. This pull request add the ability to split flink-protobuf codegen code to improve decode/encode method performance. ## Brief change log - `PbCodegenDeserializer/PbCodegenSerializer` Interface add `codegenSplit` method - Add PbCodeSplitter to split Row type code - All `PbCodegenDeserializer/PbCodegenSerializer` Impl to implement `codegenSplit` method ## Verifying this change - This change is already covered by existing tests. - add new UT test `BigProtoBufCodeSpiltterTest` ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / no) no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / no) no - The serializers: (yes / no / don't know) no - The runtime per-record code paths (performance sensitive): (yes / no / don't know) no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: (yes / no / don't know) no - The S3 file system connector: (yes / no / don't know) no ## Documentation - Does this pull request introduce a new feature? (yes / no) yes - If yes, how is the feature documented? (not applicable / docs / JavaDocs / not documented) not applicable -- This is an automated message from the Apache Git Service.
