> region_mover will call isSuccessfulScan when region has moved to make sure
> it's healthy, however , if the moved region has lots of expired data
> region_mover#isSuccessfulScan will take a long time to finish ,that may even
> exceed "lease timeout".So I made isSuccessfulScan a get-like scan to achieve
> faster response in that case.
> workaround:before graceful_stop/rolling_restart ，call major_compact on the
> table with small TTL
