-----------------------------------------
Summary: CAS not applied on rows containing an expired ttl column
Key: CASSANDRA-6363
URL: https://issues.apache.org/jira/browse/CASSANDRA-6363
Project: Cassandra
Issue Type: Bug
Components: Core
Environment: Linux/x64 2.0.2 4-node cluster
Reporter: Michał Ziemski
CREATE TABLE session (
id text,
usr text,
valid int,
PRIMARY KEY (id)
);
insert into session (id, usr) values ('abc', 'abc');
update session using ttl 1 set valid = 1 where id = 'abc';
(wait 1 sec)
And
delete from session where id = 'DSYUCTCLSOEKVLAQWNWYLVQMEQGGXD' if usr ='demo';
Yields:
[applied] | usr
-----------+-----
False | abc
Rather than applying the delete.
Executing:
update session set valid = null where id = 'abc';
and again
delete from session where id = 'DSYUCTCLSOEKVLAQWNWYLVQMEQGGXD' if usr ='demo';
Positively deletes the row.
