### Run the `movr` workload
1. Load the initial schema:
{% include copy-clipboard.html %}
~~~ shell
$ cockroach workload init movr \
'postgresql://root@localhost:26257?sslmode=disable'
~~~
2. Initialize and run the workload for 1 minute:
{% include copy-clipboard.html %}
~~~ shell
$ cockroach workload run movr \
--duration=1m \
'postgresql://root@localhost:26257?sslmode=disable'
~~~
You'll see per-operation statistics print to standard output every second:
