I made a PoC to replace our current ElasticSearch cluster with Clickhouse 20.10.
5x gains in space and 3x gains in QPS, without changing too much the schema model.
It's still in a PoC repo, priorities I guess..
Very interesting! Having worked for both Elastic and now ClickHouse, I'd love to hear more about the use case or learnings you have from the POC. If you have any questions or issues that pop up, I'd be happy to try and get an answer for you from the team.
