Description

We need an adapter to adapt flip1.RestartPipelinedRegionStrategy for legacy scheduler, so that the legacy scheduler can support fine grained recovery.

The failover recovery should respect scheduleMode(EAGER/LAZY_FROM_SOURCES) to avoid more tasks get re-scheduled than that before failover.
