There is no way to reverse a compaction.
You can initiate a user compaction on a single file though, see nodetool (i think) or the JMX interface.

A related question, is there any way to reverse a major compaction without loosing performance? Do I just have to wait it out?

Thanks Aaron for the perfect explanation. Decided to go with automatic compaction. Thanks again.

The issue with major / manual compaction is that it creates a one file. One big old file.
That one file will not be compacted unless there are (min_compaction_threshold -1) other files of a similar size. So thombstones and overwrites in that file may not be purged for a long time.
If you go down the manual compaction path you need to keep doing it.
If you feel you need to do it do it, otherwise let automatic compaction do it's thing.
