             Summary: Support ES|QL queries for Elasticsearch
                 Key: NIFI-13441
                 URL: https://issues.apache.org/jira/browse/NIFI-13441
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Chris Sampson


Elasticsearch 8.14 has made the new {{ES|QL}} [Query API](https://www.elastic.co/guide/en/elasticsearch/reference/current/esql-query-api.html) Generally Available.

This is a powerful new approach to querying Elasticsearch data, which allows users to combine data across indices and perform more logic and processing of data within Elasticsearch, rather than having to implement that within the client after data has been returned. Supporting this in NiFi would help people make better use of their data within Elasticsearch, with multiple use cases being enabled around RAG and Vector retrieval, etc.

Note that {{ES|QL}} was first introduced in Elasticsearch 8.11 (although there may have been breaking changes to the API in between), and is not known to be available in other non-Elastic services that present an Elasticsearch-like interface. This should be made clear within the NiFi processor documentation.
