----------------------------------------
Is this a duplicate of CASSANDRA-8335?
> Support UPDATE IF NOT EXIST OR compare checks in LWT transactions
> -----------------------------------------------------------------

> Key: CASSANDRA-8753
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8753
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Gerrit Jansen van Vuuren
>
> I've got a column that I want to update e.g min = x IF min > x
> but if there is no value for min e.g min == null then the update will never
> succeed, which means I need to do a READ then INSERT and then run UPDATES
> which defies the purpose of using the LWT for this use case.
> is it possible for LWT to support either IF min > x OR min == null ? or
> otherwise take null as equal to zero for numbers ?
