ASF GitHub Bot commented on FLINK-10126: ---------------------------------------- yanghua commented on issue #6738: [FLINK-10126] There should be a Scala DataSource URL: https://github.com/apache/flink/pull/6738#issuecomment-424184780 hi @StephanEwen , Before providing the API directly, I evaluated the implementation of a peer `DataSource` in the flink-scala module. However, It will break the existing source API. It was found that `ExecutionEnvironment.scala` released some `readXXX` APIs that returned `DataSet.scala`. Inside these APIs, we got a `DataSource` (flink-java) and then called `wrap(source)` to convert it to a `DataSet.scala`. Considering that there are only two or three APIs exposed in the `DataSource.java` (one of which `withParameters` has been exposed through the `DataSet`), I chose to expose the API in the `DataSource` to the `DataSet.scala` with minimal changes and without breaking the current API. In fact, in this JIRA's description, reporter is more concerned with getting the APIs provided by `DataSource.java`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
