Benjamin Lerer updated CASSANDRA-14684:
---------------------------------------
Description:
[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}
Additional information for newcomers:
Some checks should be added into {{TokenRestriction}} for the different type of
restrictions when an invalid value is found.
The unit tests should be added within {{SelectOrderedPartitionerTest}}
