> For user initiated compactions, I would like to be able to limit the number of threads that run compactions on each tablet server.  My use case is that for Fluo tables I need to periodically compact ranges of a table to garbage collect Fluo transactional data.  However, I would like these compactions to have minimal impact.
> Being able to do the following would be nice, where the {{-m}} options is the max number of compactions to run on any tablet server.
> {noformat}
>    compact -t myTable  -b p: -e p:~  -m 1
> {noformat}
> Thinking the best implementation would be to push this information to the tablet server and let it manage, rather than having the master try to coordinate.
