[graytaylor0]

Is your feature request related to a problem? Please describe.
As a user of the OpenSearch sink without for OpenSearch Serverless vector and time series collections that do not support custom document id, I would like to prevent duplicate data from entering OpenSearch.

Describe the solution you'd like
Configuration options in the OpenSearch sink that will enable querying OpenSearch for a documents that may already exist in OpenSearch to prevent duplicate documents.

- opensearch:
        ....
        query_for_existing_document:
          query_when: 'getMetadata("potential_duplicate") == true'
          query_term: 'id'
          action_on_found: drop // only option currently
          query_duration: PT3M

@graytaylor0 , Could we solve this by implementing OpenSearch as a processor to find it, then use the drop_events processor to drop it. We have #1984 opened as a request to query data from OpenSearch. That could help solve this more generically.
