Could you turn this into a psql extension? If this is integrated into an actual database that can be used in production, this may have a future. Otherwise no one will touch this, and it’d be yet another useless and cute experiment from the academia.

edit: thank you for clarifying, it looks like this is not a new database engine and is a cache/query layer.

Thanks for the helpful suggestion! EVA uses an SQL database system for managing structured data using sqlalchemy. It runs on PostgreSQL out of the box. You only need to provide the database connection url in the EVA configuration file.

Thanks for your candid comment. We take it very seriously. EVA is already being used in production by some collaborators and we would love to support more early adopters :) Please let me know if I can DM you to get more feedback.

Nice.

I’ve skimmed over the documentation and it wasn’t clear. It looked like the database was designed from scratch. If this is a caching/syntactic sugar over a mix of DB and inference queries, this is interesting and feels a lot less risky.

We designed EVA from scratch for managing unstructured data (e.g., video, audio, images, etc.). EVA leverages relational database systems to manage structured data and widely-used libraries to manage feature embeddings (FAISS library [1]). We aim to leverage decades of experience in relational database systems and reduce risk in production deployment.
