Partitioning
Kafka topics are divided into partitions, each of which is replicated across multiple brokers for fault tolerance. When a producer sends a message to a topic, Kafka needs to determine which partition of the topic the message should be sent to.
Does Kafka use Consistent Hashing?
Yes, Kafka uses consistent hashing to distribute partitions across brokers in a Kafka cluster. This approach ensures that each message is assigned to a specific partition based on a consistent hashing algorithm, which helps in achieving load balancing and fault tolerance in the Kafka cluster.
