Node configuration properties are applied individually to each node in a cluster. The following table lists each node configuration property in alphabetical order, along with its description and default setting. After you change a node-level property setting, you must restart the node for the change to take effect.
You must include the following required properties in your configuration. If you omit them,
redpanda will not start.
|data_directory||The folder where Redpanda streaming data files are stored. |
|node_id||A number that identifies the node within the cluster. This value can be assigned automatically by a deployment tool, or it can be assigned by the user. Each node must have a unique |
|admin||Address and port of the admin server. |
|admin_api_doc_dir||Path to the admin API documentation directory. |
|admin_api_tls||TLS configuration for the admin HTTP server. |
|advertised_kafka_api||Address of Kafka API published to clients. |
Default: an empty array.
|advertised_rpc_api||Address of the RPC endpoint published to other cluster members. |
|cloud_storage_cache_directory||The directory where the cache archive is stored. This property is mandatory when cloud_storage_enabled is set to true. |
|coproc_supervisor_server||IP address and port for supervisor service. |
|dashboard_dir||The directory where the HTTP dashboard is located. |
|developer_mode||Skips most of the checks performed at startup. Not recommended for production use. |
|kafka_api||Address of the Kafka API that handles requests. |
|kafka_api_tls||Transport Layer Security (TLS) configuration for the Kafka API endpoint. |
|rack||A rack is a label that identifies a failure zone. Apply the same label to all nodes in the same failure zone. When enable_rack_awareness is set to true at the cluster level, the system uses the rack labels to spread partition replicas across different failure zones. |
|rpc_server||Remote Procedure Call (RPC) server IP address. |
|rpc_server_tls||TLS configuration for RPC server. |
|seed_servers||List of the seed servers used to join the current cluster. If the seed_servers list is empty, the node will be a cluster root and it will form a new cluster. |
