Coming from Solr, I was able to remove a core with the command:
curl -d -v "http://<HOST>:<PORT>/solr/admin/cores?action=UNLOAD&core=<CORE_NAME>"
With DSE, I use the column family name for <CORE_NAME>, but I get an "Unload is not supported!" response.
What's the best way to remove a column family completely from both Solr and Cassandra?
