[jira] [Created] (IGNITE-12091) Rebalance load should be spread across the cluster

Anton Vinogradov (Jira)
Anton Vinogradov created IGNITE-12091:
-----------------------------------------

             Summary: Rebalance load should be spread across the cluster
                 Key: IGNITE-12091
                 URL: https://issues.apache.org/jira/browse/IGNITE-12091
             Project: Ignite
          Issue Type: Task
            Reporter: Anton Vinogradov


Currently, suppliers are selected randomly between the owners and this may lead to
- unbalanced grid load
- unbalanced per-supplier supplying data amount

So, we have to
- seek to have the same partitions amount to be supplied by each supplier during same rebalance
- seek to have the same partitions amount per supplier for each demander
- demander should seek to demand partitions from the maximum amount of suppliers

Seems we have to implement some function able to calculate global rebalance distribution.
