>                 Key: CASSANDRA-10537
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10537
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Nimi Wariboko Jr.
>              Labels: CQL
>             Fix For: 2.1.x

> Conditional updates currently do not support CONTAINS and CONTAINS KEY conditions. Queries
such as 
> {{UPDATE mytable SET somefield = 4 WHERE pk = 'pkv' IF set_column CONTAINS 5;}}
> are not possible.
> Would it also be possible to support the negation of these (ex. testing that a value
does not exist inside a set)?
