In Big Data, an enormous volume of data is used. Regarding data, we have two main challenges.The first challenge is how to collect large volume of data and the second challenge is to analyze the collected data. To overcome those challenges, you must need a messaging system.
Kafka is designed for distributed high throughput systems. Kafka tends to work very well as a replacement for a more traditional message broker. In comparison to other messaging systems, Kafka has better throughput, built-in partitioning, replication and inherent fault-tolerance, which makes it a good fit for large-scale message processing applications.
What is a Messaging System? A Messaging System is responsible for transferring data from one application to another, so the applications can focus on data, but not worry about how to share it. Distributed messaging is based on the concept of reliable message queuing. Messages are queued asynchronously between client applications and messaging system. Two types of messaging patterns are available − one is point to point and the other is publish-subscribe (pub-sub) messaging system. Most of the messaging patterns follow pub-sub.

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.
Core Capabilities
High Throughput
Deliver messages at network limited throughput using a cluster of machines with latencies as low as 2ms. Scalable
Scale production clusters up to a thousand brokers, trillions of messages per day, petabytes of data, hundreds of thousands of partitions. Elastically expand and contract storage and processing. Permanent storage
Store streams of data safely in a distributed, durable, fault-tolerant cluster. High availability
Stretch clusters efficiently over availability zones or connect separate clusters across geographic regions.
Ecosystem
Built-in Stream Processing
Process streams of events with joins, aggregations, filters, transformations, and more, using event-time and exactly-once processing. Connect To Almost Anything
