----------------------------------------------------------
In which version will this funcnaility be available? I am on cassandra 3.11 and dosent seem to work
Also if I have query
select col1, col2, col3 from table A
v/s
select map['keycol1'],map['keycol2'],map['keycol3'] from table A
Would both the queries have equivalent performance ?
