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. Developed by the Apache Software Foundation, Kafka was initially developed at LinkedIn and became a part of the Apache project in 2011. Kafka is designed to handle real-time data feeds with low latency and high efficiency. It is beneficial for tracking service calls (like clicks or page views on a website) or tracking IoT sensor data.

• Kafka can be spread across multiple servers for a higher degree of fault tolerance. The distributed nature of Kafka makes it incredibly scalable -- you can increase the capacity of your applications by simply adding more servers to them.
• Kafka works in real time, with the messages available to subscribers immediately after being published.
• Messages in Kafka are redundant and replicated across multiple nodes, making the system resilient to node failures.
• Kafka persists messages on the disk, which provides intra-cluster replication. Hence messages continue on disk as fast as possible, preventing data loss.
• Kafka supports the processing of high volumes of messages to keep real-time data feeds.
