	## Projects Using Ristretto
	Below is a list of known projects that use Ristretto:
	- [Badger](https://github.com/dgraph-io/badger) - Embeddable key-value DB in Go
	- [Dgraph](https://github.com/dgraph-io/dgraph) - Horizontally scalable and distributed GraphQL database with a graph backend
	- [Vitess](https://github.com/vitessio/vitess) - Database clustering system for horizontal scaling of MySQL
	- [SpiceDB](https://github.com/authzed/spicedb) - Horizontally scalable permissions database

Vitess is no longer using Ristretto, as per vitessio/vitess#13939

The poor hitrate performance of Ristretto is probably caused by some of the unfixed bugs which we’ve discussed during the call

Neither is SpiceDB 🤔 which is using a fork https://github.com/authzed/spicedb/blob/57bf05e1c63d8df16ccf571ce90200f9ce92fc1d/go.mod#L56
