Kibana for various data sources


I know currently kibana supports only elasticsearch.

Caravel ( was started only for druid, but now extended to various datasources(jdbc, elasticsearch, etc..) .
Zeppelin ( support various datasource connections.

Are there or Were there any discussion about this , kibana for various datasources, far future, great imagination?

This sounds like a feature request ;). I would submit this to github (, with some context and added explanation to how you would like to see Kibana use other datasources.

That said, I am not sure if there were ever any. A lot of Kibana's core functionality is very tied to Elasticsearch. For example, Sense/Dev Tools to write ES queries, or the visualizations which tie into the aggregations API, etc...
