actix/r2d2 on the Rust side (I haven't worked out bb8 yet), aiohttp/uvloop/asyncpg/gunicorn on the Python side (Postgres for the DB). This kinda _is_ the cache at present, it's a distillation of a lot of other data into a given form. Rust's async story re: databases still looks a little up-in-the-air right now from an outside perspective though, so I guess I'll wait and see how it pans out. It's definitely a work in progress and I didn't expect this much interest in my offhand "I tried Rust even though I couldn't see myself using it for real, but..." comment.
