Subject Re: Cluster auto activation design proposal
Date Wed, 09 Aug 2017 21:33:52 GMT
Sergey,

That’s the only concern I have:

* 5. User takes out nodes from cluster (e.g. for maintenance purposes): no
  rebalance happens until user recreates BLT on new cluster topology.*

What if a node is crashed (or some other kind of outage) in the middle of the night and the
user has to be sure that survived nodes will rearrange and rebalancing partitions?
