+### Stress test for zipkin3 service_span_name_index table
+###
+### Stress testing is done using the `cassandra-stress` tool
+###
+### For example
+###  cassandra-stress  user profile=span_name_by_service-stress.yaml ops\(insert=1\)  duration=1m  -rate threads=4 throttle=50/s
+###
+### after a benchmark has been run with only writes, a mixed read-write benchmark can be run with
+###  cassandra-stress  user profile=span_name_by_service-stress.yaml ops\(insert=1,select=1,select_span_names=1\)  duration=1m  -rate threads=4 throttle=50/s
+
+# Keyspace Name
