Kibana without elasticsearch?

As we know elasticsearch stores, search and analyses data and then show it on kibana , But i ahve my data is already stored in postgresql and we have to deal with huge data then storing it in elasticsearch for seeing graph on kibana is not good . there will be duplicacy like we have same data in postgres as well as in elasticsearch and i have huge data(full traffic from a telecom company) and we want to build a reporting tool . Kibana has all the features that we want but we dont want this duplicacy of data ... i mean we want to use only Kibana. Is it possible? and what should i do to avoid this problem ?? what are the possibilities??

It's only compatible with ES.

For it to work with anything else would require a near-complete rewrite.

ok so it means we cant use it beacause we cant afford this duplicacy of data. can you suggest me some alternative?

No idea sorry, maybe try a postgres forum?
