What is Kafka?  

Kafka is one of the fastest-growing open-source distributed streaming platforms developed by the Apache Software Foundation, which has built a huge ecosystem around it. It is designed to handle high-throughput, fault-tolerant, and real-time data streaming.   

Many technology leaders agree that it is a powerful abstraction for building web applications and architecture. It allows producers to publish streams of records for one or more topics and consumers to subscribe to those topics and process the records in real-time. Kafka guarantees fault tolerance and durability by replicating data across a configurable number of servers that too in a cluster.  

And, you know what? It can handle trillions of events per day. Just amazing!   

It has unique characteristics that make it a very attractive option for data integration. Kafka offers persistent storage of messages, allowing consumers to process data at their own pace and ensuring data durability even in the event of consumer failures.  

Kafka is a scalable distributed streaming software development platform that enables enterprises to create real-time data feeds. Industries use Kafka for processing payments, collecting customer interactions, tracking metrics, and processing data streams.
