brokers # role object required *
This struct represents a role - e.g. HDFS datanodes or Trino workers. It has a key-value-map containing all the roleGroups that are part of this role. Additionally, there is a config, which is configurable at the role and roleGroup level. Everything at roleGroup level is merged on top of what is configured on role level. There is also a second form of config, which can only be configured at role level, the roleConfig. You can learn more about this in the Roles and role group concept documentation.
