As we know Elasticsearch stores, search and analyses data and then shows it on Kibana. But I have my data already stored in PostgreSQL and we have to deal with huge data, so storing it in Elasticsearch for seeing a graph on Kibana is not good. There will be duplication 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 don't want this duplication 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?
