>
> If we start major compaction on a big table first,
> then we modified compaction limit configuration and execute 'update_config'
> command,
> it will not effective immediately.
> The compaction which is running is still use the old Controller object.
> The higher.bound,lower.bound,offPeakHours is still the old value.
>
> I think we can make the modification effective immediately.
> There is 2 points about it:
> 1.keep there is always only one PressureAwareCompactionThroughputController
> object in RS.
> 2.add a updateConfig method in Controller.
> when we use 'update_config' command to update compact pressure conf , it just
> change the value of higher.bound,lower.bound,offPeakHours ,instead of create
> a new Controller
