Apache Kafka
Apache Kafka is an open source platform for stream processing. The software was originally developed by LinkedIn and written in the programming languages Scala and Java. In 2011, Kafka became part of the Apache foundation. The software was named after the author Franz Kafka because it represents a system optimized for writing.
The aim of the project is to provide a unified platform with high throughput and low latency for processing real-time data feeds. Kafka can connect to external systems and, with Kafka Streams, offers stream processing in Java.
Kafka is widely used in real-time streaming data architectures to provide real-time analytics. It is defined for:
- Publication and subscription to data streams
- Effective storage of data streams
- Process streams in real time
As the software is a fast, scalable and fault tolerant publish-subscribe messaging system, Kafka is used in use cases where the message systems Java Message Service (JMS), RabbitMQ and AMQP may not be considered due to the volume and responsiveness. Kafka offers higher throughput and reliability properties and is therefore suitable for high data volumes with which conventional Message Oriented Middleware (MOM) may be overwhelmed.
