Foreign key constraints are now generally available

Today, we are announcing that foreign key constraints are generally available on PlanetScale within any unsharded database. Foreign key constraints can be used to enforce referential integrity in your database. During our beta phase in the last two months, over 2,400 PlanetScale databases have enabled foreign key constraints. You can read more about our foreign key constraints support in the PlanetScale documentation. Previously, we wrote about how we overcame the technical challenges of support

Amazon Aurora Pricing: The many surprising costs of running an Aurora database

Amazon describes Aurora as a scalable database that's simple to manage, but if you've ever gone through the "Create database" wizard, you know that's not quite an accurate statement. From instance types to storage configurations to monitoring your database, there is much to consider when trying to price an Amazon Aurora cluster. In this article, we'll cover all the little details you'll need to understand the Amazon Aurora pricing model to get an accurate estimate for an Aurora database. The inf

Video generation models as world simulators

We explore large-scale training of generative models on video data. Specifically, we train text-conditional diffusion models jointly on videos and images of variable durations, resolutions and aspect ratios. We leverage a transformer architecture that operates on spacetime patches of video and image latent codes. Our largest model, Sora, is capable of generating a minute of high fidelity video. Our results suggest that scaling video generation models is a promising path towards building general
