Lars Hofhansl commented on HBASE-8329:
--------------------------------------
Cool!
Couple of questions:
* can we do with fewer config options? F.e. do need a separate control size?
Can that be the lower bound?
* compaction are in the end run per store. Should the speed decision be made on
a store by store basis, based on the number of store files for this store?
* should we take compaction min/max/blocking files into account? Maybe compact
faster when we're over the blocking file count.
* another way to configure is to specify or detect the speed on the NIC, and
then just limit compactions to a percentage of that. Would that be easier to
understand?

> There is no speed or resource limit for compaction，I think we should add this
> feature especially when request burst.
