Event Streaming (Kafka)

Event Streaming (Kafka)

Apache Kafka is a distributed event streaming platform used for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications.

Key Concepts

• •Topics & Partitions: Messages are published to topics, which are partitioned across brokers for parallel processing.
• •Producer/Consumer: Producers write data to topics. Consumers read from topics. Decouples data generation from data consumption.
• •Consumer Groups: Consumers coordinate to consume a topic's partitions. Each partition is consumed by only one member per group.
• •Retention: Kafka stores messages durably on disk for a configured period, allowing replayability unlike traditional queues.

Real-World Applications

Uber (telemetry), Netflix (viewing history), LinkedIn (activity tracking) use Kafka for massive real-time event streaming.
