------------------------------

             Summary: Custom Receiver for Structured streaming
                 Key: SPARK-26213
                 URL: https://issues.apache.org/jira/browse/SPARK-26213
             Project: Spark
          Issue Type: New Feature
          Components: Spark Core
    Affects Versions: 2.4.0
            Reporter: Aarthi


Hi,

I have implemented a Custom Receiver for a https/json data source by implementing the Receievr abstract class as provided in the documentation here [https://spark.apache.org/docs/latest//streaming-custom-receivers.html]

This approach works on Spark streaming context  where the custom receiver class is passed it receiverStream. However I would like the implement the same for Structured streaming as each of the DStreams have a complex structure and need to be joined with each other based on complex rules. ([https://stackoverflow.com/questions/53449599/join-two-spark-dstreams-with-complex-nested-structure])

 Structured streaming uses the Spark Session object that takes in DataStreamReader which is a final class. Please advice on how to implement the custom receiver for Strucutred Streaming. 

Thanks,
