It is truly a tremendous feat of engineering, product, and project management to build a solution of this magnitude in just a year. I believe fluid cross-team communication, and excellent foresight in flagging future issues and design decisions are some of the ingredients that led ClickHouse to such flawless execution.
Space launch 'commoditization', JWST, AI/NLP advancements (regardless the current hype), mRNA vaccines are real examples of "truly a tremendous feat of engineering".
Running a database on Kubernetes backed by an object based storage? Not even close.
Don't get me wrong, Clickhouse folks are great and their DB is fantastic, but your scale may need some adjustments.
