Key Concepts of Kafka

Kafka is a distributed event store and streaming platform that has become essential for large-scale data pipelines at companies like Netflix and Uber. The core architecture consists of messages organized into topics and partitions, with producers writing data and consumers reading it in groups. Brokers form clusters that handle message storage and replication for reliability. Key advantages include support for multiple producers and consumers, disk-based retention for durability, and horizontal scalability. However, challenges include complex configuration options, inconsistent tooling, limited client library maturity outside Java/C, and lack of true multi-tenancy.
