It seems that “younger generation” programmers underestimate the value of governance in OSS. The recent Terraform kerluffle couldn’t have happened if Terraform was in the ASF, etc.
3 of 7 work at EDB, and the core team doesn’t drive the project roadmap. And EDB hackers fail to get patches in all the time, just like everyone else :)
I’ve personally deployed O(TBs) and O(10^4 TPS) Postgres clusters on Kubernetes with a CNPG-style operator based deployment. There are some subtleties to it but it’s not exceeding complicated, and a good project like CNPG goes a long way to shaving off those sharp edges. As other commenters have suggested it’s good to really understand Kubernetes if you want to do it, though.
The PG community is a lot of things, but I think “dominated by commercial interests” is not one of them.
Disclosure: I work at EDB :)
