    Description

      • disable the balancer
      • prohibit external users from causing migrations via moveChunk

      Add an optional isFrozen fieldĀ  for each collection in config.collections.
      isFrozen = true overrules the noBalance field for the collection if specified (even if noBalance = false, isFrozen = true disallows the balancer from running)
