Benjamin Lerer commented on CASSANDRA-14344:
--------------------------------------------
{quote}Just want to check if it is expected to support multi-column IN
restriction too on clustering keys.{quote}
We do not support it for the slice operator ({{>}}, {{>=}}, {{<= }} and {{<}})
so it make no sense to support it for the {{IN}} restrictions.
> Support the IN restrictions on indexed columns
