      Description

      When performing a merging minor compaction, the smallest file for a tablet is chosen, and then data to be minor compacted is merged with said small file.

      When the smallest file isn't actually small, this can cause extremely large/long minor compactions. I don't want to completely "disable" merging minor compactions, for as I continue to run ingest, I'd like to take advantage of merging the small files together via minc.

      An upper bound on the file size to merge seems the most straightforward means to control this.
