             Summary: GetElasticsearch processor invokes elasticsearch GET api without an identifier when flow file is null
                 Key: NIFI-10303
                 URL: https://issues.apache.org/jira/browse/NIFI-10303
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Vijaya Gorla


Right now, all update operations on Elasticsearch with the PutElasticsearchRecord/Json processors use [the partial document update approach|https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update.html#_update_part_of_a_document]. The content of the flow file is added as the {{doc}} in the update request by the [ElasticSearchClientServiceImpl|https://github.com/apache/nifi/blob/d79b3908360265eb0d50a5ce298a00c3054cdf82/nifi-nar-bundles/nifi-elasticsearch-bundle/nifi-elasticsearch-client-service/src/main/java/org/apache/nifi/elasticsearch/ElasticSearchClientServiceImpl.java#L281].

Can there also be provided an option to [add a script to the update request|https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update.html#update-api-desc]? Using script updates [is supported in the Elasticsearch {{_bulk}} API|https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html#bulk-update], so it should be possible to add this feature.
