Make sure you have started PD and TiKV, then run:

```
./benchdb -run="create,truncate,insert:0_10000,update-random:0_10000:100000,select:0_10000:10"
./benchdb -run="create|truncate|insert:0_10000|update-random:0_10000:100000|select:0_10000:10"
```


### Arguments

#### `run`
The `run` argument defines the workflow of the test. You can define
multiple jobs, separated by `,`. The jobs are executed sequentially.
