  • controller.quorum.voters
  • requestTimeoutMs
  • retryBackoffMs
  • electionTimeoutMs
  • electionBackoffMaxMs
  • fetchTimeoutMs
  • appendLingerMs

RaftConfig is created when:


A comma-separated list of {id}@{host}:{port} with the node IDs and the endpoints of all the controllers (quorum voters) in a Kafka cluster in a KRaft mode (e.g., 1@localhost:9092,2@localhost:9093,3@localhost:9094)

Default: (empty)
