PlanetScale adds dedicated, configurable read replicas for Postgres

planetscale.com by Etienne Berube et al. Editor score 7/10

The replicas asynchronously copy from a primary and can be sized and targeted individually, including in other regions to serve nearby readers. The feature gives engineers another way to distribute read load and reduce latency.

What: PlanetScale now offers dedicated Postgres read replicas that replicate asynchronously from a primary cluster.
How: Teams can configure each replica's instance size and disk characteristics, and create credentials targeting replicas individually.
Why it matters: Dedicated replicas can direct regional reads closer to clients or isolate vector-search and analytics workloads from primary traffic.

The primary cluster replicates data to dedicated replicas, which can serve client read traffic. Sketched from the article's own text.
