Custom plugins sometimes require custom mappings/settings.  
As an example, elastiknn requires a [specific setting](https://elastiknn.com/api/#index-settings) to enable the plugin for a given index and a [custom field mapping](https://elastiknn.com/api/#general-structure) for the configuration.

With the Rest High-Level Client, this can be done using **XContentFactory**. The new Elasticsearch Java Client is much more elegant and type-safe but it does not seem to support custom settings/mappings.

Is there any plan to support this?

Thanks

Yes, definitely. We've done some prototyping on this already which is captured in [[roadmap] Add support for plugin-defined custom components · Issue #252 · elastic/elasticsearch-java · GitHub](https://github.com/elastic/elasticsearch-java/issues/252)

Please subscribe to that issue to follow its progress. Feedback is of course welcome!
