Subject Passing a custom SourceContext to a SourceFunction
Date Wed, 15 May 2019 07:30:07 GMT
Hi -

I have a custom SourceFunction ..

class MySourceFunction[T](data: Seq[T]) extends SourceFunction[T] {
  def run(ctx: SourceContext[T]): Unit = {
    data.foreach(d ⇒ ctx.collect(d))
  }
}

When this function is run during job execution, the SourceContext that gets
passed serializes the data. I would like to pass a mock SourceContext
(similar to
https://github.com/apache/flink/blob/master/flink-streaming-java/src/test/java/org/apache/flink/streaming/api/functions/ListSourceContext.java)
in the run method. How do I do this ? Note I am not invoking the run method
explicitly anywhere.

Any help will be appreciated.

regards.
