Konstantin updated CASSANDRA-15345:
-----------------------------------
Description:
The below example conditional update is wrongly evaluated to True and applied
even though clustering key 'k1' is not present in the table:
CREATE KEYSPACE test_keyspace WITH replication = \{'class': 'SimpleStrategy',
'replication_factor': 1};
CREATE TABLE test_table (id int, k text, version int static, v text, PRIMARY
KEY (id, k));
INSERT INTO test_table(id, version) VALUES (0, 0);
SELECT * FROM test_table;
id | k | version | v
----+------+---------+------
0 | null | 0 | null
(1 rows)
SELECT * FROM test_table WHERE id=0 AND k='k1';
id | k | version | v
----+---+---------+---
(0 rows)
UPDATE test_table SET v='foo', version=1 WHERE id=0 AND k='k1' IF version = 0;
[applied]
-----------
True
SELECT * FROM test_table;
id | k | version | v
----+----+---------+-----
0 | k1 | 1 | foo
(1 rows)
DROP TABLE test_table;
DROP KEYSPACE test_keyspace;
