You can make ANY standard receiver sleep by implementing a custom Message Deserializer class with sleep method inside it.

Why not just trigger your batch job with that event? If you really need streaming, then you can create a custom receiver and make the receiver sleep till the event has happened. That will obviously run your streaming pipelines without having any data to process.

My question is: it looks like the DStream will be started right after the StreaminContext has been started. Is it possible to delay the start of specific DStream?
