Apache Spark is a fast and general-purpose cluster computing system. In Spark, we can do the batch processing and stream processing as well. It does near real-time processing. It means that it processes the data in micro-batches. I have discussed more Spark Streaming in my previous blog. Now in this blog, I'll discuss Stateful Streaming in Spark. So let's start !!
What Is Stateful Streaming?
Stateful stream processing means that a "state" is shared between events and therefore past events can influence the way current events are processed.
