dawidwys opened a new pull request #8549: [FLINK-12604][table-api][table-planner] Register TableSource/Sink as CatalogTables URL: https://github.com/apache/flink/pull/8549 ## What is the purpose of the change This is next step in decoupling `TableEnvironment` from Calcite. It introduces registration of `TableSource/Sink` as `CatalogTable`s. ## Brief change log This is based on #8521. - added `org.apache.flink.table.catalog.ConnectorCatalogTable` that wraps `TableSource/Sink` and used it for registration in `TableEnvironment` - added `org.apache.flink.table.operations.TableSourceTableOperation` for reading from an inline `TableSource`. This is used only when creating a `Table` from `TableEnvironment#fromTableSource` - removed unnecessary code duplication from classes such as `TableSourceSinkTable`, `TableSourceTable`, `TableSinkTable` etc. ## Verifying this change * This change is already covered by existing tests. * Added test to verify `TableEnviroment#fromTableSource` behavior: `org.apache.flink.table.runtime.stream.table.TableSourceITCase#testInlineCsvTableSource` ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
