> If I had to only pick two databases to deal with, I’d be quite happy with just Postgres and ClickHouse - the former for OLTP, the latter for OLAP.
As the author mentioned, I completely agree with this statement. In fact, many companies like Cloudflare are built with exactly this approach and it has scaled them pretty well without the need of any third database.
> Another reason I suggest checking out ClickHouse is that it is a joy to operate - deployment, scaling, backups and so on are well documented - even down to setting the right CPU governor is covered.
Another point mentioned by author which is worth highlighting is the ease of deployment. Most distributed databases aren't so easy to run at scale, ClickHouse is much much easier and it has become even more easier with efficient storage-compute separation.
