Hi everybody, I wanted to raise attention to CASSANDRA-19637 <https://issues.apache.org/jira/browse/CASSANDRA-19637> that I already mentioned in the "[DISCUSS] NULL handling and the unfrozen collection issue" thread.
The patch attempts to fix some inconsistencies in the way LWT conditions work with collections when being compared to null values. In case you feel that the solution is not going in the right direction or you believe that there are some valid use cases that will be impacted by this change in behavior feel free to raise the problem.
