For example, if we create a Topic with the replication-factor set to 3, the leader of the topic will be already maintaining the first copy. Next, it shows a list of the replicas. Pub/sub allows you to broadcast data across multiple processes but has no way of scaling processing since every message goes to every subscriber.

Kafka enables both the above models through “Consumer group” concept making it scalable in processing and a multi-subscriber. Description. It is available inside your bin directory. Css Whatever you type now in the terminal, the producer will send that to the broker. That means, when a producer wants to send some data, it connects with the leader and starts sending data. Function For every partition, we have a leader and the leader takes care of all the requests and responses. Its fairly understandable syntax makes it highly approachable. if you still use the old consumer implementation, replace --bootstrap-server with --zookeeper. Selector We use a specific term for making multiple copies in Kafka, called “replication-factor”. Some of these commands are not working. Kafka distributes partitions evenly over the available brokers. bootstrap.servers is a comma-separated list of host and port pairs that are the addresses of the Kafka brokers in a "bootstrap" Kafka cluster that a Kafka client connects to initially to bootstrap itself. bootstrap-servers vs zookeeper.
