qryn, signoz and highlight are all built on top of clickhouse. I think they all have done a good job of leveraging clickhouse instead of building something from the ground up. That is a super smart thing.

We think that managing clickhouse is extra effort. Direct access to object storage is vital for cost reduction which is somewhat difficult in clickhouse. Small resource footprint is extremely valuable to many too. Simplicity of deployment is key to get started and many will use a product simply because they can. I know, I have used products that simply ran, and for no other reason.

Our best wishes to all the 3 teams.
