I'll second Simplicity and add in that ClickHouse is also faster on less hardware and more stable compared to our current Druid configuration. My company currently uses Druid and has for a few years now, but I have been evaluating ClickHouse on the side as a possible replacement, and as a testament to its simplicity, I was able to stand it up and get in going as a PoC pretty quick/easily. So far I have only found good things about ClickHouse, maybe the only ClickHouse downside has been the management of the cluster and data, but I haven't gotten too far into operationalizing ClickHouse to know how much those kind of items will cost. Perhaps the other thing is the documentation, while reasonably good imo, still doesn't explain everything as well as I'd like. It was good enough, but I definitely had to experiment on a couple items to get them working as needed.
