Kafka - Brokers and Topics đ
Description đ
A Kafka cluster is composed of multiple brokers (servers). Each broker is identified with its ID (integer). Each broker contains certain topic partitions. Partitions are distributed across all the brokers in the Kafka cluster. This is what makes Kafka scale, and is called horizontal scaling. You only need to connect to one broker and the Kafka clients will know how to be connected to the entire cluster. Each broker knows about all brokers, topics, and partitions (metadata). This is called cluster bootstrapping.
