In an event driven architecture you have to perform an action to stop the event in a controlled manner. That ( say) streamingContext.stop() or for that matter streamingContext.stop(stopGracedully=True) won't cause any stop by itself. *You need to build in a mechanism *to tell spark streaming to pr

Hi Mich, thanks a ton for your kind response, looks like we are still using the earlier methodologies for stopping a spark streaming program gracefully. Regards, Gourav Sengupta On Wed, May 5, 2021 at 6:04 PM Mich Talebzadeh wrote: > > Hi, > > > I believe I discussed this in this forum. I sen

Hi, I believe I discussed this in this forum. I sent the following to spark-dev forum as an add-on to Spark functionality. This is the gist of it. Spark Structured Streaming AKA SSS is a very useful tool in dealing with Event Driven Architecture. In an Event Driven Architecture, there is genera
