Kafka is the high-performance TCP protocol server used for large distribution of servers to clients. It is used to collect, store, retrieve, and scale large amounts of data. One of the prior advantages of this technology, Kafka, is that it streams massive messages in Low Latency. Kafka is written in Java and Scala. It can be deployed as bare hardware, virtual machines, and containers as well as in cloud environments.
