> h3. Motivation
> Core idea is to rebalance table data after some topology events. Distribution zones both provide corresponding triggers and set of nodes to perform affinity recalculation, meaning that dataNodes _change_ is a trigger and dataNode _state_ is an input for an affinity recalculation. Thus it's required for partition to listen for such events though ms watches and call old-fashioned rebalance logic.
> *Definition of Done*
> Rebalance is performed after dataNodes changes.
