# Regression test for SCYLLADB-81.

# Unlike regular secondary indexes, vector indexes do not use materialized views
# in their implementation, therefore they do not need the keyspace
# to be rf-rack-valid in order to function properly.
# 
# In this test, we check that creating a vector index without
# rf_rack_valid_keyspaces being set is possible.
