In this course, Processing Streaming Data with Apache Spark on Databricks, you’ll learn to stream and process data using abstractions provided by Spark structured streaming. First, you’ll understand the difference between batch processing and stream processing and see the different models that can ...
Most data streams, though continuous in flow, have discrete events within streams, each marked by a timestamp when an event transpired. As a consequence, this idea of “event-time” is central to howStructured StreamingAPIs are fashioned for event-time processing—and the functionality they offe...
