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`.

> In Java, an ExecutionEnvironment's createInput method returns a DataSource,
> whereas the Scala version returns a DataSet. There is no Scala DataSource
> wrapper, and the Scala DataSet does not provide the Java DataSource methods,
> such as getSplitDataProperties.
