Pricing for pg should be easy to compute 20M vectors @768 is about 62GB, for 32bit, not even quantized. AWS RDS will put it at 83USD/m (db.t4g.small, 2vcpu 2GB RAM). But that's not with egress, backups, etc Seems acceptable at least for a POC? A better option if you already have the data in the same instance, but developer experience being low scares me. Anyone tried it? How did it go? |

Vector indexes are very large, almost the size of the original data, and that needs to fit into the database memory ideally.
