Since the newer Java client is just a wrapper around the REST API, that
should make it pretty robust to work against many ES 5 clusters, right? We've
been telling folks that the other ES5 processors only support 5.0.x clusters
due to the native nature of the transport client, and the ESHttp processors are
right for other cluster versions. If this new processor should work against
many ES5 clusters, and is using the REST API under the hood, I wonder if we
should call it JsonQueryElasticsearch5Http for consistency, what do you think?
> Create a new ElasticSearch processor that supports the JSON DSL

> Key: NIFI-4325
> URL: https://issues.apache.org/jira/browse/NIFI-4325
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Mike Thomsen
> Priority: Minor
>
> The existing ElasticSearch processors use the Lucene-style syntax for
> querying, not the JSON DSL. A new processor is needed that can take a full
> JSON query and execute it. It should also support aggregation queries in this
> syntax. A user needs to be able to take a query as-is from Kibana and drop it
> into NiFi and have it just run.
