Description

Motivation

According to IEP-131 DisasterRecoveryManager#resetPartitions will be the core method for recovering partition majority availability. Current logic of this method schedules new rebalance where it tries to restore replica factor after reset. For the purposes of IEP-131 this method must only reset without scheduling, so DisasterRecoveryManager#resetPartitions must be improved with some kind of flag and if this flag is HA, replica factor should not be recovered.

Definition of Done

• resetPartitions must be improved and it must be possibile to not schedule replica factor restoration for HA mode
