------------------------------------
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.
