If I have a table in cassandra where the schema is like the following:
name varchar
email list(text)
If I have a list of email addresses for each name, how do I get the size of the list for the user? Like if user1 has e1@yahoo.com and e2@gmail.com. The list would contain these two emails. What I want is that it returns 2 for the number of emails the user has. I'm using Cassandra 2.0.
