Alex Petrov reassigned CASSANDRA-10537:
---------------------------------------
Assignee: Alex Petrov
> CONTAINS and CONTAINS KEY support for Lightweight Transactions
> --------------------------------------------------------------
>
> Key: CASSANDRA-10537
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10537
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Nimi Wariboko Jr.
> Assignee: Alex Petrov
> Labels: CQL
> Fix For: 3.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)?
