Apache Kafka vs ClickHouse

Apache Kafka is an open-source distributed event streaming platform used for building real-time data pipelines and streaming applications. Originally developed at LinkedIn, it provides high-throughput, fault-tolerant publish-subscribe messaging with persistent storage. Kafka supports stream processing through Kafka Streams and ksqlDB.

ClickHouse is an open-source column-oriented database management system optimized for analytical queries and real-time data processing at scale. It provides exceptionally fast query performance through data compression and vectorized query execution.
