> We should expose a region level metric that represents max refCount among
> refCounts of all compacted store files under the region. For successful
> archival of compacted store files, it is important for this metric count to
> be 0 eventually if not immediately. If it is >0 for a considerably high
> amount of time, it indicates some issue i.e. reader refCount leak on some
> compacted store files and in such case, archival would not be successful.
