That aside. Can anyone explain WHAT they are? If they were done away with in Cassandra then they must have been surplus to requirements. In which case, why have them originally? They must have been there for some reason.

For future reference - it's "generally CQL API compatible". That's the extent of it. It's analogous to driving a make/model of one car and taking it to a completely different unrelated dealer for maintenance because they're both cars. Just because the interface to use them (steering wheel, doors, engine, 4 tires) is broadly the same, the internals are wildly different.
