  • I happen to like this article by Jon Haddad discussing how "safe" you really are with ACID: http://rustyrazorblade.com/2015/06/youre-already-eventually-consistent/ – Aaron Aug 05 '15 at 15:31
  • Why do you think ACID operations are mandatory? – takendarkk Aug 05 '15 at 17:16

Companies use Cassandra when they need their application to scale to use many servers for higher capacity and higher reliability by keeping redundant copies of data on multiple servers.

In many cases ACID transactions are not needed for building a correctly functioning system.

Databases which have good support for ACID transactions are often limited to a single server, so they do not scale.
