I'm thinking whether we should add a tooltip for new users.
Maybe simply saying that works with ch cloud and what works with oss clusters

[serprex]

mirror validation could check for host being CHC

[heavycrystal]

should be possible with CheckIfClickHouseCloudHasSharedMergeTreeEnabled

[serprex]

That only runs when we're in clickpipes. Validation here is for OSS peerdb users with CHC destination

[heavycrystal]

yes I mean we can use that function outside of current codepath to get if a service is SMT which should mean we disable these engines

[serprex]

I think for now we can omit this, people using CHC should know this engine doesn't apply to them

[heavycrystal]

lgtm as an experiment
