문제

I'm new to cassandra, so this may be a trivial question.

Given a table defined as follows: create table Users ( username text, props map, PRIMARY KEY (username) );

Can I use individual elements of the map in a where clause? (i.e. select * from users where props['is_online']='no';)

I've seen examples referencing individual elements on updates and deletes, but haven't been able to find anything regarding usage as part of the where clause.
