The configuration on the management node on a mysql ndb cluster is cached by default and not reread on start/restart.

I think about disabling it, because people keep forgetting to explicit reload the configuration when adding nodes.

But I am not sure why it exists and dont want to change it without knowing what problem solves.

As it is activated by default there is probably a good reason for it?

All management nodes must agree to use the same configuration, if the cache is off and a node is restarted with a different configuration does it still take on the other node(s) (old) configuration? –  KCD Jan 28 at 1:14
