-----------------------------------------
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.
