Attachment: CASSANDRA-21067_Fixup_PAXOS_substraction.patch
> C* 4.1.10 LWT does not support the substraction
> ------------------------------------------------

> Key: CASSANDRA-21067
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21067

> Issue Type: Bug
> Reporter: vincent royer

>
>
> C 4.1 does not support the minus operation in LWT. See below:
> docker run --name cassandra-41 -d cassandra:4.1.10-jammy
> docker exec -it cassandra-41 cqlsh
> cqlsh> create KEYSPACE toto WITH replication = \{'class':
> 'NetworkTopologyStrategy','datacenter1':'1'};
> cqlsh> use toto;
> cqlsh:toto> create table t1 (pk int primary key, a int);
> cqlsh:toto> insert into t1 (pk, a) VALUES ( 1,1);
> cqlsh:toto> update t1 set a = a + 1 WHERE pk=1;
> cqlsh:toto> update t1 set a = a + 1 WHERE pk=1 IF EXISTS;
> [applied]
> -----------
> True
> cqlsh:toto> update t1 set a = a - 1 WHERE pk=1 IF EXISTS;
> InvalidRequest: Error from server: code=2200 [Invalid query] message="Invalid
> operation (a = a - 1) for non counter column a"
>
> The code is correct in C 5.x, but C* 4.1 branch probably had a merge issue
> and does not play any unit test with a substraction in a LWT.
