What is Apache Kafka

Advantages

System reliability

Kafka allows reliable messaging through its distributed structure. All messages are stored on disks that require replication within the cluster (backup from one source to another).

High performance

Kafka Streams technology allows you to process large amounts of data. It’s achieved by the fact that each time data is read from a particular topic, a new thread is created that creates a topic to write data already read and processed there.

Open source

Kafka is part of the Apache Software Foundation project line and continues to develop actively due to the large developer community.
