Clickhouse is *really* gatekeeping the "zero copy replication" where you store data on object-storage and have high availability from the open source version.
This is the main driver for their cloud ;-)
How? Have you tried contributing a reasonable implementation with test coverage and it was rejected?
I think that is just the nature of the open core business - but like most such businesses, they're not very clear about how that is what they are, pretending to be open source business instead.
