  RabbitHAQueues:
    description:
      The number of HA queues to be configured in rabbit. The default is -1 which
      translates to "ha-mode all". The special value 0 will be automatically
      overridden to CEIL(N/2) where N is the number of nodes running rabbitmq.

      The number of seconds to configure the value of the erlang
      net_ticktime kernel variable.

    type: number
  RabbitAdditionalErlArgs:
    description:
      Additional parameters passed to the Erlang subsystem. The string
      needs to be enclosed in quotes twice. We default to +sbwt none
      in order to have the erlang vm be less busy on spinlocks, but
      we allow a simple way of overriding it.
