Hello, For example, I have cluster made of number of replicaSets. Each replicaSet have backup servers inside, with priority 0 in order to do only backup job. It would be also nice idea to make priority levels also working for electing as BalancerHost in the cluster instead of specifying exact Balancers. Thank you, |

The balancer now runs on the config server, so this has gone away. |

Can we change ticket's status to "Waiting for bug fix"? Thank you, |

I would better say, I want priorities for cluster balancing election between mongos working the same way as priorities in replicaSets between mongod. |

Would it be fair to say that you want a mongos instance that won't act as a balancer at all for that use? |

No, there is any performance issues. |

The balancer doesn't actually move the data so there shouldn't be much io, nor cpu to act as the balancer. Is there a performance issue when the balancer runs on the backup node? |
