Learn Kafka with online courses and programs
What is Kafka?
Apache Kafka is an event streaming platform designed to handle and deliver massive amounts of data. Originally developed for LinkedIn, Kafka began as an internal system to handle the social media platform’s daily messages. Today, Apache Kafka is an open-source data streaming solution that can take data from multiple sources and deliver that data to consumers.Footnote 1
Apache Kafka processes data in real time from all kinds of sources: databases, sensors, mobile devices, and more. These event streams are then stored for retrieval, processing, and routing to various destinations. With event streaming, developers can create applications to process online payments, track shipments, predict patient outcomes, and react to customer interactions in real time.Footnote 2
The Kafka architecture can be scaled up by adding new nodes or servers. Kafka is written in Java and Scala, and Kafka Streams, a Java stream processing library which makes it a natural and intuitive tool for developers already working with these programming languages. This platform is also compatible with other programming languages, making it a versatile and widely used tool.
Kafka’s core APIs allow developers to customize the way that their software operates. For example, the Admin API can manage and inspect Kafka objects while the Producer API writes a stream of events. The Kafka Connect API allows developers to build and run data import and export connectors that read and write event streams to and from external systems. This allows these external systems to integrate with the Kafka platform as well as apps and systems already in place.Footnote 3
