Also, the architecture of Aurora is very different from PlanetScale's:
* AWS Aurora uses storage-level replication, rather than traditional Postgres replication. This architecture has the benefit that a change made on an Aurora primary is visible very quickly on the read replicas. * PlanetScale is a "shared nothing" architecture using what I would call traditional methods of data replication, where the primary and the replicas have independent copies of the data. This means that replication lag is a possibility customers must consider, whereas Aurora customers mostly ignore this. * If you set up 3 AWS RDS Postgres instances in separate availability zones and set up replication between them, that would be roughly similar to PlanetScale's architecture.
Scaling postgres is not that informative. I am sorry if I annoyed the people working on it. I think the USP could be explained more obviously.
More features will come later on which I think will set us apart even more from RDS, Aurora and other providers, but too early to talk about those.
Beyond features, there are other reasons you might choose us. For example, we've built a reputation on being having excellent reliability/uptime, with exceptionally good support. These are harder to back up with hard data, but our customer testimonials are a good testament to this.
