             Summary: ElasticsearchHttp processors should support dynamic properties as query parameters
                 Key: NIFI-4218
                 URL: https://issues.apache.org/jira/browse/NIFI-4218
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Matt Burgess
            Priority: Minor


The Elasticsearch HTTP API has a number of fields that can be specified as query parameters in the URL, such as support for [pipelines|https://www.elastic.co/guide/en/elasticsearch/reference/current/ingest.html]. Rather than including all possibilities as processor properties, it might be more flexible to allow the user to specify dynamic properties on ElasticsearchHttp processors, and then use those to set query parameters on the API URL.

Documentation should include a note that not all features are available to all versions of Elasticsearch, and thus the ES documentation should be consulted before adding dynamic properties. For example, pipelines were introduced in ES 5.x, so using pipeline parameters in an ElasticsearchHttp processor will not work if connecting to an ES 2.x cluster.
