Supports [template snippets]({{site.url}}{{site.baseurl}}/ingest-pipelines/create-ingest/#template-snippets). The metadata fields `_index`, `_version`, `_version_type`, and `_id` cannot be removed. If `version` is specified, `_id` cannot be removed from the ingested document. | `exclude_field` | Optional | The field name to be retained. All other fields, except metadata fields, will be removed. The `exclude_field` and `field` options are mutually exclusive. Supports [template snippets]({{site.url}}{{site.baseurl}}/ingest-pipelines/create-ingest/#template-snippets). | `description` | Optional | A brief description of the processor. | `if` | Optional | A condition for running the processor. | `ignore_failure` | Optional | Specifies whether the processor continues execution even if it encounters errors. If set to `true`, failures are ignored. Default is `false`. | `on_failure` | Optional | A list of processors to run if the processor fails. | `tag` | Optional | An identifier tag for the processor. Useful for debugging in order to distinguish between processors of the same type. | ## Using the processor Follow these steps to use the processor in a pipeline. **Step 1: Create a pipeline** The following query creates a pipeline, named `remove_ip`, that removes the `ip_address` field from a document: ```json PUT /_ingest/pipeline/remove_ip { "description": "Pipeline that excludes the ip_address field.", "processors": [ { "remove": { "field": "ip_address" } } ] } ``` {% include copy-curl.html %} **Step 2 (Optional): Test the pipeline** It is recommended that you test your pipeline before you ingest documents. {: .tip} To test the pipeline, run the following query: ```json POST _ingest/pipeline/remove_ip/_simulate { "docs": [ { "_index": "testindex1", "_id": "1", "_source":{ "ip_address": "203.0.113.1", "name": "John Doe" } } ] } ``` {% include copy-curl.html %} **Response** The following example response confirms that the pipeline is working as expected: ```json { "docs": [ { "doc": { "_index": "testindex1", "_id": "1", "_source": { "name": "John Doe" }, "_ingest": { "timestamp": "2023-08-24T18:02:13.218986756Z" } } } ] } ``` **Step 3: Ingest a document** The following query ingests a document into an index named `testindex1`: ```json PUT testindex1/_doc/1?pipeline=remove_ip { "ip_address": "203.0.113.1", "name": "John Doe" } ``` {% include copy-curl.html %} **Step 4 (Optional): Retrieve the document** To retrieve the document, run the following query: ```json GET testindex1/_doc/1 ``` {% include copy-curl.html %}
