We have imported most of our data about config options from Cassandra. Due to that, many options that mention the database by name are still using "Cassandra". Specially for the user visible options, which is something that a user sees, we should really be using Scylla here. This patch was created by automatically replacing every occurrence of "Cassandra" with "Scylla" and then later on discarding the ones in which the change didn't make sense (such as Unused options and mentions to the Cassandra documentation) Signed-off-by: Glauber Costa <glauber@scylladb.com> Message-Id: <1423e1d7e36874a1f46bd091aec96dcb4d8482d9.1468267193.git.glauber@scylladb.com>
