I need a local, persistent key/value store that works well with Go. 

Transaction support is not needed, I will just do simple atomic reads/writes to implement a local cache of data fetched from a farcaster hub (ex: fid->fname, castId->cast_data, etc)

It would be nice (not required) if it provided some pruning mechanism out of the box that lets me prune entries after a specific number of entries is reached.

I'm open to test something that fits the requirements but it's not 100% battle-tested, my app is not mission critical and can easily recover if things break once in a while.

Yes, I'm leaning towards badger after looking around for options.

I'm not too deep in db comparison land, but I've had good experience with badger. I use it in a few projects for the same purpose of being a fast enough, local, simple cache including in my farcaster tui

Do you need it to be persisted for a long time or just read / write? It might be somewhat of an overkill (almost always is) but I love the interface of etcd.

The context it will be used is fargo (farcaster command line client that uses Farcaster gRPC API). I currently cache requests (for example looking up fids or fnames) using an in-memory map that I just dump on disk. I'm looking for something similarly simple, but more manageable and maybe a couple of additional features out of the box.

It will be an overkill to have a separate service for this. 🙏
