Hi @DrissiReda. Kibana is very tightly coupled to Elasticsearch so I think adapting Kibana to use a different database such as Clickhouse would be a very difficult task. If you must use Clickhouse, may I suggest using Grafana instead?
If you are not completely reliant on Clickhouse, perhaps you can use one of the many integrations in the Elastic Stack instead? You can sign up for a free trial of Elastic Cloud to try it out.
