Out of curiosity, have you compared SSDB via MinIO (as another commenter mentions)?

Asking because we use MinIO, and for us (a small online place with a single actually active MinIO server) it's been pretty good + super stable.

Hadn't heard of MinIO. We looked into another S3 caching solution that someone linked in comments here, but it came down to we already used SSDB in production. Also, a personal preference of mine is to keep all logic in the same layer: Python.

For ex: We use SQLAlchemy as the source of truth for our relational database schema, and we use Alembic to manage database schema changes in Python. We even shard our Postgres tables in Python [1]. It fits with my preference to keep this caching logic also in Python, by reading/writing directly to the cache and S3 from the Python app and workers.

Can Minio act as a caching proxy? Or do you do something manual like publishing to minio first, and then later publishing to S3 in batch or something?

edit: Found this https://docs.min.io/docs/minio-gateway-for-s3.html

Awesome! So minio can actually act as a caching proxy for S3. Very cool.
