-----------------------------------------
Summary: C* 4.1.10 LWT does not support the substraction
Key: CASSANDRA-21067
URL: https://issues.apache.org/jira/browse/CASSANDRA-21067
Project: Apache Cassandra
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.
