 proxy | No | String | The address of a [forward HTTP proxy server](https://en.wikipedia.org/wiki/Proxy_server). The format is "<host name or IP>:<port>". Examples: "example.com:8100", "http://example.com:8100", "112.112.112.112:8100". Port number cannot be omitted.
 index | Conditionally | String | Name of the export index. Applicable and required only when the `index_type` is `custom`.
 index_type | No | String | This index type tells the Sink plugin what type of data it is handling. Valid values: `custom`, `trace-analytics-raw`, `trace-analytics-service-map`, `management-disabled`. Default value is `custom`.
-template_type | No | String | Defines what type of OpenSearch template to use. The available options are `v1` and `index-template`. The default value is `v1`, which uses the original OpenSearch templates available at the `_template` API endpoints. The `index-template` option uses composable [index template]({{site.url}}{{site.baseurl}}/opensearch/index-templates/) which are available through OpenSearch's `_index_template` API. Composable index types offer more flexibility than the default and are necessary when an OpenSearch cluster has already existing index templates. Composable templates are available for all versions of OpenSearch and some later versions of Elasticsearch. 
-template_file | No | String | The path to a JSON [index template]({{site.url}}{{site.baseurl}}/opensearch/index-templates/) file such as `/your/local/template-file.json` when `index_type` is set to `custom`.  For an example template file, see [otel-v1-apm-span-index-template.json](https://github.com/opensearch-project/data-prepper/blob/main/data-prepper-plugins/opensearch/src/main/resources/otel-v1-apm-span-index-template.json). If you supply a template file it must match the template format specified by the `template_type` parameter.
+template_file | No | String | Path to a JSON [index template]({{site.url}}{{site.baseurl}}/opensearch/index-templates/) file (for example, `/your/local/template-file.json`) if `index_type` is `custom`. See [otel-v1-apm-span-index-template.json](https://github.com/opensearch-project/data-prepper/blob/main/data-prepper-plugins/opensearch/src/main/resources/otel-v1-apm-span-index-template.json) for an example.
 document_id_field | No | String | The field from the source data to use for the OpenSearch document ID (for example, `"my-field"`) if `index_type` is `custom`.
 dlq_file | No | String | The path to your preferred dead letter queue file (for example, `/your/local/dlq-file`). Data Prepper writes to this file when it fails to index a document on the OpenSearch cluster.
 dlq | No | N/A | DLQ configurations. See [Dead Letter Queues]({{site.url}}{{site.baseurl}}/data-prepper/pipelines/dlq/) for details. If the `dlq_file` option is also available, the sink will fail.
