twalthr opened a new pull request #7409: [FLINK-11064] [table] Setup a new flink-table module structure URL: https://github.com/apache/flink/pull/7409 ## What is the purpose of the change This commit splits the `flink-table` module into multiple submodules in accordance with FLIP-28 (step 1). The new module structure looks as follows: ``` flink-table-common ^ | flink-table-api-base ^ | flink-table-api-java/scala <-- flink-table-planner --> flink-table-runtime | `-> Calcite ``` The module `flink-table-planner` contains the content of the old `flink-table` module. From there we can distribute ported classes to their final module without breaking backwards compatibility or force users to update their dependencies again. If a user wants to implement a table program in Scala, `flink-table-api-scala` and `flink-table-planner` need to be added to the project. If a user wants to implement a UDF or format, `flink-table-common` needs to be added. If a user wants to implement a table source, `flink-table-api-java` and `flink-table-planner` need to be added for now. But soon only `flink-table-api-java` is required (see FLIP-28 step 5). All Flink modules have been updated to the new dependency design. End-to-end tests succeed and docs have been updated. ## Brief change log - Update modules `flink-table` modules ## Verifying this change This change is already covered by existing tests, such as SQL Client, Streaming SQL e2e tests. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): yes - 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? docs
