## Amazon OpenSearch Serverless
The `opensearch` source can be configured with Amazon OpenSearch Serverless by setting the `serverless` option to `true`, as shown in the following example:
```yaml
- opensearch:
hosts: [ 'https://1234567890abcdefghijkl.us-west-2.aoss.amazonaws.com' ]
aws:
sts_role_arn: 'arn:aws:iam::123456789012:role/my-domain-role'
region: 'us-west-2'
serverless: true
```
## Using metadata
When the `opensource` source constructs Data Prepper events from documents in the cluster, the document index is stored in the EventMetadata with an `opensearch-index` key, and the document_id is stored in the `EventMetadata` with the `opensearch-document_id` as the key. This allows for conditional routing based on the index or `document_id`. The following example pipeline configuration sends events to an `opensearch` sink and uses the same index and `document_id` from the source cluster as in the destination cluster:
