wuchong opened a new pull request #8029: [FLINK-11898] [table-planner-blink] Support code generation for all Blink built-in functions and operators URL: https://github.com/apache/flink/pull/8029 ## What is the purpose of the change Support code generation for all Blink built-in functions and operators. ## Brief change log changes to `flink-table-planner-blink` - Add `BinaryStringCallGen` include `generate...` methods for BinaryString. - Add `ScalarFunctionGens` for generate function using `BuiltinMethods`. - Register all the Blink built-in SqlFunctions to `FlinkSqlOperatorTable` changes to `flink-table-runtime-blink` - Add `SqlDateTimeUtils` to place all the date time related methods. - Add `SqlFunctionUtils` to place all the other builtin methods. - Add Calcite Avatica dependency to `flink-table-runtime-blink` because we need Avatica's `TimeUnitRange` and `DateTimeUtils` when in runtime `SqlDateTimeUtils`. ## Verifying this change - We add a lot of expression tests under `org/apache/flink/table/expressions` to test built-in functions. - Move all the IT tests in `BuiltinScalarFunctionITCase` (in blink repository) to `ScalarFunctionsTest` unit tests to save test time. ## 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)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - 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? (no) - If yes, how is the feature documented? (not applicable)
