> We want a pretty in-depth canary that will try every region on a cluster. When doing
that for the whole cluster one machine is too slow, so we wanted to split it up and have each
regionserver run a canary. That works however the canary does less work as it just tries one
random region.
> Lets add a flag that will allow the canary to try all regions on a regionserver.
