Apache Kafka - Real-time Stream Processing (Master Class) - Kafka Streams Architecture

This lecture covers Apache Kafka Streams, focusing on its parallel processing and fault tolerance capabilities. It explains the difference between single-threaded and multithreaded applications, and how to configure them for vertical and horizontal scaling. The concept of stream tasks and topology is introduced, with an example illustrating task assignment and scaling. Finally, the lecture discusses fault tolerance, explaining how Kafka Streams handles failures by reassigning tasks to running instances.
