That’s incredible. I wasn’t expecting them to allow you to run AlloyDB on premise but this is a potential game changer for on-prem Postgres instances, especially if you are doing analytical queries on the same data set.
That's how I've been thinking/talking about it. It should be a drop-in replacement for Postgres. Obviously the install process isn't as smooth yet, but, technical preview...
Eh, there are other options for this that are more mature and more likely to be supported in the long run. The Citus columnar store extension has been around for almost a decade.
I looked at the citus columnar however lack of updates and deletes even occasionally kept me away.
