> 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.
