Description

It is not possible to insert an empty map. It looks like the "{}" is reserved only for Set.

So when for table:

CREATE TABLE users (
    id text PRIMARY KEY,
    surname text,
    favs map<text, text>
)

I try to insert map without any elements:

cqlsh:test> insert into users(id,surname,favs) values('aaa','aaa',{});

I get:

 Bad Request: Set operations are only supported on Set typed columns, but org.apache.cassandra.db.marshal.MapType(org.apache.cassandra.db.marshal.UTF8Type,org.apache.cassandra.db.marshal.UTF8Type) given.
