Subject [jira] [Commented] (CASSANDRA-14684) Queries with a clause involving tokens and Long.MIN_VALUE include rows incorrectly
Date Fri, 31 Aug 2018 14:02:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-14684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16598757#comment-16598757

Benedict commented on CASSANDRA-14684:
--------------------------------------

This query should probably be rejected, as Long.MIN_VALUE is not a valid token.

>             Project: Cassandra

> [cqlsh 5.0.1 | Cassandra 2.2.9 | CQL spec 3.3.1 | Native protocol v4]
> When running a CQL query where we filter on a token compared to -9223372036854775808
(the minimum value for a long), the filter appears to have no effect.
> For example:
> {code:java}
> SELECT token(user_id) FROM events WHERE token(user_id) = -9223372036854775808 LIMIT 3;
> system.token(user_id)
>  -----------------------
>   -9223371814601747988
>   -9223371814601747988
>   -9223371814601747988
> {code}
> It doesn't matter whether `=`, `<`, `<=`, `>` or `>=` are used in the comparison,
the results appear the same.
> In contrast, if using `Long.MIN_VALUE + 1`, it returns no results as expected: 
> {code:java}
> SELECT token(user_id) FROM events WHERE token(user_id) <= -9223372036854775807 LIMIT
3;
> system.token(user_id)
> -----------------------
> (0 rows)
> {code}
