What is Apache Kafka?
Apache Kafka is an open-source distributed event streaming platform used by thousands of companies for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications. It delivers messages with latency as low as 2ms on a cluster of machines, and stores data streams safely in a distributed, durable, fault-tolerant cluster. It has built-in stream processing such as joins, aggregations, filters, and transformations, and connects to hundreds of event sources and sinks through the Connect interface. It is one of the five most active projects of the Apache Software Foundation.
- High throughput with latency as low as 2ms
- Scales to thousands of brokers and trillions of messages per day
- Distributed, durable, fault-tolerant persistent storage
- High availability across availability zones and regions
- Built-in stream processing based on event time and exactly-once
- Kafka Connect for connecting to Postgres, JMS, Elasticsearch, AWS S3, and more
- Client libraries for many programming languages
Who uses Apache Kafka and for what
- High-performance data pipelines and data integration
- Streaming analytics
- Mission-critical applications that need ordering guarantees and no message loss
