 What is Kafka? Event and Message streaming platform Yes, It is open-source and freely available. There are some commercial availabilities also.  Producers( AKA publishers) push messages/events to Kafka Consumers( AKA subscribers) listen & receive messages/events Publisher ?? Subscriber ??  Don't worry. Let's take a look at it before digging deep. 😊 Publisher Subscriber Pattern. Consider below case. A sender sends message to the receiver.  Sender needs to know the receiver address ( means receiver address should configure in Sender side) Both parties should agreed upon common protocol/format for data sending and receiving.  Now see this case,  Now 3 receiver addresses should configure in sender side.  And if you need to add a new one, then sender side also has a change to be done.  Imagine multiple sender sending multiple receivers ,  Yes. the configuration is a mess now. It is not easy to add a new receiver because there can be many sen...
