Cassandra data model in two lines.

Lots of people don't get the Cassandra data model. Hope this helps:
[Keyspace] [CF] [Key] [Column]
[Keyspace] [CF] [Key] [SuperColumn][SubColumn]
Yes, the nomenclature is thoughtlessly confusing, but it pre-dates Cassandra so you might as well get used to it.

If you have no idea what I am talking about then this post is clearly not aimed at you :-P

  1. Thanks!
    The weird thing: as soon as you understand it, it's easy... if you don't, it doesn't make 100% sense

    But this certainly helped me :)

  2. The main problem is that the APIs are so badly designed they utterly fail to convey this rather simple concept.
