Kafka is a messaging system built for high throughput and fault tolerance.
Kafka has a built-in patriation system known as a Topic.
Kafka Includes a replication feature as well.
Kafka provides a queue that can handle large amounts of data and move messages from one sender to another.
Kafka can also save the messages to storage and replicate them across the cluster.
For coordination and synchronization with other services, Kafka collaborates with Zookeeper.
Apache Spark is well supported by Kafka
