Founder here -- this is about our warehouse product which is separate from our main analytics DB. Our DuckDB warehouse was used by a handful of pilot customers. Our clickhouse database is serving all of our analytical queries.

If this is a pilot program for a small number of users, the blog post would feel a lot more logical.

As it was written, it looks like the engineering team is migrating the core infrastructure of the company around.

Try VictoriaLogs for your warehouse product next time. It provides efficient storing and querying petabytes of wide events with hundreds of fields - see https://docs.victoriametrics.com/victorialogs/keyconcepts/ , and it provides very easy scaling path from single-node setup to cluster setup, so you can start with an instance per customer and then gradually scale to many storage nodes as workload grows - https://docs.victoriametrics.com/victorialogs/cluster/#singl... .
