----------------------------------------
Summary: Trigger rebalance on zone.dataNodes change
Key: IGNITE-18088
URL: https://issues.apache.org/jira/browse/IGNITE-18088
Project: Ignite
Issue Type: Improvement
Reporter: Alexander Lapin
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.
