In our previous blog, we compared Apache Flink® and Apache Kafka® Streams. Now, let’s compare Kafka Streams and Apache Spark Structured Streaming!  How can ride-sharing applications display up-to-the-moment vehicle availability and price for thousands of concurrent ride requests? How do financial institutions detect anomalies that signal fraud in real time among millions of other transactions? And how do video streamers track subscriber behavior, user taste, and preferences across billions of hours of streaming content?     The answer in each case begins with data stre ..read more
