I’ve never used Cassandra, but a quick google turns up a jdbc compliant
driver. So thats where i’d start
https://code.google.com/a/apache-extras.org/p/cassandra-jdbc/
install that, along with any dependencies in your /lib directory, restart
lucee/tomcat and then create a datasource of type “Other” with a type
of “org.apache.cassandra.cql.jdbc.CassandraDriver”.
