> 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 configurable.
> 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.
