Subject [jira] [Commented] (CASSANDRA-6363) CAS not applied on rows containing an expired ttl column
Date Sat, 16 Nov 2013 14:47:22 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13824487#comment-13824487

Aleksey Yeschenko commented on CASSANDRA-6363:
----------------------------------------------

You are missing statements in your description, and as a result it doesn't make a lot of sense
(is it one partition or two? why different ids then?)

>                 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: MichaƂ 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.
