If you want to write results to multiple keys, you can do so by defining multiple `redis.write` subsections in the `output` section of the job file. Each instance of `redis.write` can specify a different key, data format, and other parameters. For example, you can create two different keys for the same data, one with a default key format and another with a custom key format and mapping.

```yaml
name: Write to multiple keys with different formats
output:
  - uses: redis.write
    with:
      # Setting data_type to JSON and using the default key format
      data_type: json

  - uses: redis.write
    with:
      data_type: json

      # Defining a custom key format
      key:
        language: jmespath
        expression: concat(['events-simplified:id:', id])

      # And defining a custom mapping
      mapping:
        - id: id
        - name: name
        - location: location
```
