Sylvain Lebresne commented on CASSANDRA-10532:
----------------------------------------------
bq. What dev should we assign for LWT stuff?
Not sure, but you can feel free to assign me for triaging. In this instance,
unless I'm missing something, we shouldn't need any change to the underlying
LWT implementation, this is really more of a CQL issue.
> Allow LWT operation on static column with only partition keys

> Project: Cassandra

> Schema
> {code:sql}
> CREATE TABLE IF NOT EXISTS achilles_embedded.entity_with_static_column(
> id bigint,
> uuid uuid,
> static_col text static,
> value text,
> PRIMARY KEY(id, uuid));
> {code}
> When trying to prepare the following query
> {code:sql}
> DELETE static_col FROM achilles_embedded.entity_with_static_column WHERE
> id=:id_Eq IF static_col=:static_col;
> {code}
> I got the error *DELETE statements must restrict all PRIMARY KEY columns with
> equality relations in order to use IF conditions, but column 'uuid' is not
> restricted*
> Since the mutation only impacts the static column and the CAS check is on the
> static column, it makes sense to provide only partition key
