Can anybody explain Apache Kafka for me in a plain language? I'd appreciate an explanation with a practical example instead of abstract theoretical definitions, then I can understand better. What is it used for? What does messaging mean? Messaging between what?!! At which stage of a BigData analysis is it used? And what are prerequisites for learning it? PS: Please explain as you would explain for a non-technical person

I am a beginner in Apache Kafka. I am reading now some architecture documents and I find in a diagram 2 components: Kafka Channel Kafka Broker What is the difference between these 2 components?

Does Apche Kafka support sockets-based communication? Example: After running both Kafka producer and consumer.if I send a message through putty(TCP/IP client), will the consumer receive it or not?
