1. Basic Selection

• Get field: device.name
• Get nested field: app.plugin_type
• Get first of array: data.values[0]

2. Filter and Projection (Common)

• Filter: items[?type=='telemetry']
• Projection: items[].name

3. Common Ways of Combined Output

JMESPath returns JSON value, you can write the result directly to an out_path.

TIP

If you find yourself "Wanting to concat strings/do complex calculation", this usually means you need stronger Transform (Not supported yet). You can output necessary fields to JSON first, then handle on platform side.
