This patch enables select cql statements where collection columns are selected columns in queries where clustering column is restricted by "IN" cql operator. Such queries are accepted by cassandra since v4.0. The internals actually provide correct support for this feature already, this patch simply removes relevant cql query check. Tests: cql-pytest (testInRestrictionWithCollection) Fixes #7743 Fixes #4251 Signed-off-by: Vojtech Havel <vojtahavel@gmail.com> Message-Id: <20210104223422.81519-1-vojtahavel@gmail.com>
