You can do this by defining a `mapping` section in the output configuration.\n\n[code example]\n\nThe example above remaps the `CustomerId` field to `id`, `FirstName` to `first_name`, and `LastName` to `last_name` in the output. This allows you to customize the field names in the Redis data store according to your application's requirements.\nYou can also use `mapping` to include only the fields you need in the output and exclude the rest.\n\nMapping only allows you to rename fields and limit the output to specific fields and define a single level structure. To create nested structures and/or perform operations on the field values you can use the [map transformation]()."
