Noticed in the NoSQL section that they still call Cassandra as wide column DB. It’s not true for a long time - CQL requires schema definition, and although it’s possible to emulate old behavior, it’s not wide column anymore - people just copy old things...
I'm not 100% sure, but I think LinkedIn still uses it as a wide column store. At least, they've been using it a very long time and certainly used it that way before.
