twalthr opened a new pull request #11034: [FLINK-15802][table] Support new type inference for table functions URL: https://github.com/apache/flink/pull/11034 ## What is the purpose of the change Enables the new type inference for table functions. The PR conists of two commits. The first commit refactors the code generation around table functions such that return data type and argument data type are read from the function at the same location instead of reading each in a separate code generator. This adds an additional runtime collector that is only responsible for result conversion. All existing tests pass after this change. The second commit further develops the stack based on `BridgingSqlFunction` and the new type inference. Similar to FLINK-15487, we don't test every data type combination yet. ## Brief change log See commit messages. ## Verifying this change This change is already covered by existing tests, such as `CorrelateITCase`. Additional tests added in `FunctionITCase`. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: yes - The serializers: no - The runtime per-record code paths (performance sensitive): yes - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? yes - If yes, how is the feature documented?
