      Description

      One of the problems with the current compaction queue is that we have a very low granularity on the importance of the various compactions in the queue. If a StoreFile count exceeds 15 files, only then do we bump via enum change. We should instead look into more intelligent, granular priority metrics for choosing the next compaction.
