Description

mKahaDB allows multiple journals to be use, with differing QOS. However the broker storeUsage is shared across all instances.
It would be great to have a storeUsage per kahaDB instance such that particular destinations can be restricted to a subset of the available disk space while others are unlimited.
In other words, have diskUsage in the mix as a QOS metric.
