RVR-ES-502

1. Issue Summary:

   • The error "External Error - Scroll Deletion Failure" with error code RVR-ES-502 is encountered using the Elasticsearch data connector. This error indicates a failure in deleting a scroll session in Elasticsearch. Scroll sessions are used for retrieving large amounts of data from Elasticsearch, and if these sessions aren't properly closed, it can lead to the described error.

2. Action Steps:

   • Check Elasticsearch Logs: Examine Elasticsearch logs for more detailed error messages that might provide additional context about the failure. Elasticsearch logs usually provide stack traces or error messages when a failure occurs.
   • Verify Scroll Usage: Ensure that scroll sessions are being properly closed after data retrieval. This is typically done by sending a DELETE request to the _search/scroll API with the scroll ID to clean up the session.
   • Resource Management: Check if there are sufficient resources available on the Elasticsearch nodes. Sometimes, resource constraints can cause operations to fail. Consider increasing memory allocation or scaling the cluster if resource limits are being hit.
   • Elasticsearch Version: Ensure that you are using a compatible version of Elasticsearch as required by Rivery and your configurations match the documentation requirements .
