Apache Kafka - Real-time Stream Processing (Master Class) - Advanced Kafka Producers (Exactly Once)

This video tutorial covers advanced Kafka producer concepts, focusing on message durability, replication, and semantics. It explains how Kafka ensures message durability through replication and discusses the implications of at least once, at most once, and exactly once semantics. The tutorial also details the idempotent producer configuration, which helps prevent message duplication and loss, emphasizing the importance of proper application-level design to avoid duplicates.
