Renames an existing field. If the field doesn’t exist or the new name is already used, an exception will be thrown.


| Name             | Required | Default | Description                                                                                                                                                                                                                    |
|------------------|----------|---------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `field`          | yes      | -       | The field to be renamed. Supports [template snippets](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2454/manage-data/ingest/transform-enrich/ingest-pipelines#template-snippets).                              |
| `target_field`   | yes      | -       | The new name of the field. Supports [template snippets](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2454/manage-data/ingest/transform-enrich/ingest-pipelines#template-snippets).                            |
| `ignore_missing` | no       | `false` | If `true` and `field` does not exist, the processor quietly exits without modifying the document.                                                                                                                              |
| `override`       | no       | `false` | If `true`, the processor will update pre-existing non-null-valued fields. When set to `false`, such fields will not be touched.                                                                                                |
| `description`    | no       | -       | Description of the processor. Useful for describing the purpose of the processor or its configuration.                                                                                                                         |
| `if`             | no       | -       | Conditionally execute the processor. See [Conditionally run a processor](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2454/manage-data/ingest/transform-enrich/ingest-pipelines#conditionally-run-processor). |
| `ignore_failure` | no       | `false` | Ignore failures for the processor. See [Handling pipeline failures](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2454/manage-data/ingest/transform-enrich/ingest-pipelines#handling-pipeline-failures).       |
| `on_failure`     | no       | -       | Handle failures for the processor. See [Handling pipeline failures](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2454/manage-data/ingest/transform-enrich/ingest-pipelines#handling-pipeline-failures).       |
| `tag`            | no       | -       | Identifier for the processor. Useful for debugging and metrics.                                                                                                                                                                |
