Some more info:
- running C* 3.9
- I tried `nodetool flush` on the column family this change applies to, and
while it does seem to trigger compactions, there is still one pending that
won't seem to run
- I tried `nodetool compact` on the column family as well, with a similar
affect
Is there a way to tell when/if the local node has successfully updated the
compaction strategy? Looking at the sstable files, it seems like they are
still based on STCS but I don't know how to be sure.
Appreciate any tips or suggestions!
