> Currently we have only one thread for both large and small file cleaning, but when write
pressure is huge we might need more cleaner threads, so we need to make the thread number
> We observed more than 1.8PB data in archive directory online due to business access rate
change, and this proposal is one of the necessary changes required.
> Default value of the configurations would still be left to 1 to keep low pressure to
NN for normal case.
