| Configuration Name | Possible Values | Notes |
|---|---|---|
| process.roles | null broker controller broker,controller | If this is null (absent) then we are in legacy mode. Otherwise, we are in KIP-500 mode and this configuration determines what roles this process should play: broker, controller, or both. |
| controller.listener.names | If non-null, this must be a comma-separated list of listener names. When communicating with the controller quorum, the broker will always use the first listener in this list. | A comma-separated list of the names of the listeners used by the KIP-500 controller. This configuration is required if this process is a KIP-500 controller. The legacy controller will not use this configuration Despite the similar name, note that this is different from the "control plane listener" introduced by KIP-291. |
| listeners | A comma-separated list of the configured listeners. For example, INTERNAL://192.1.1.8:9092, EXTERNAL://10.1.1.5:9093, CONTROLLER://192.1.1.8:9094 | This configuration is now required. |
| sasl.mechanism.controller.protocol | SASL mechanism used for communication with controllers. Default is GSSAPI. | This is analogous to sasl.mechanism.inter.broker.protocol, but for communication with the controllers. |
| controller.quorum.voters | If non-null, this must be a comma-separated list of all the controller voters, in the format: {controller-id}@{controller-host):{controller-port} | When in KIP-500 mode, each node must have this configuration, in order to find out how to communicate with the controller quorum. Note that this replaces the "quorum.voters" config described in KIP-595. This configuration is required for both brokers and controllers. |
| controller.id | a 32-bit ID | The controller id for this server. Only required if this server is a controller. |
| broker.id | a 32-bit ID | The broker id for this server. Only required if this server is a broker. |
| initial.broker.registration.timeout.ms | 60000 | When initially registering with the controller quorum, the number of milliseconds to wait before declaring failure and exiting the broker process. |
| broker.heartbeat.interval.ms | 3000 | The length of time between broker heartbeats. |
| broker.session.timeout.ms | 18000 | The length of time that a broker lease lasts if no heartbeats are made. |
| metadata.log.dir | If set, this must be a path to a log directory. | This configuration determines where we put the metadata log. if it is not set, the metadata log is placed in the first log directory from log.dirs. |
| controller.quorum.fetch.timeout.ms | Maximum time without a successful fetch from the current leader before a new election is started. | New name for quorum.fetch.timeout.ms |
controller.quorum.election.timeout.ms | Maximum time without collected a majority of votes during the candidate state before a new election is retried | New name for quorum.election.timeout.ms |
| controller.quorum.election.backoff.max.ms | Maximum exponential backoff time (based on the number if retries) after an election timeout, before a new election is triggered. | New name for quorum.election.backoff.max.ms |
| controller.quorum.request.timeout.ms | Maximum time before a pending request is considered failed and the connection is dropped | New name for quorum.request.timeout.ms |
| controller.quorum.retry.backoff.ms | Initial delay between request retries. This config and the one below is used for retriable request errors or lost connectivity and are different from the election.backoff configs above | New name for quorum.retry.backoff.ms |
| controller.quorum.retry.backoff.max.ms | Max delay between requests. Backoff will increase exponentially beginning from quorum.retry.backoff.ms | New name for quorum.retry.backoff.max.ms |
