## Using the log

In this example, we're running 256 writers against the log to add 1024 new leaves within 1 minute.

Note that the writes are sent to the HTTP server we brought up in the previous step, but reads are sent directly to the file system.

```shell
go run ./hammer \
--log_public_key=Test-Betty+df84580a+AQQASqPUZoIHcJAF5mBOryctwFdTV1E0GRY4kEAtTzwB \
--log_url=http://localhost:2024/ \
--max_read_ops=0 \
--num_writers=256 \
--max_write_ops=256 \
--max_runtime=1m \
--leaf_write_goal=1024 \
--show_ui=false
```

Optionally, inspect the log using the woodpecker tool to see the contents:

```shell
go run github.com/mhutchinson/woodpecker@main --custom_log_type=tiles --custom_log_url=http://localhost:2024/ --custom_log_origin=Test-Betty --custom_log_vkey=Test-Betty+df84580a+AQQASqPUZoIHcJAF5mBOryctwFdTV1E0GRY4kEAtTzwB
```
