memdb
Usage Notes
- Fully ephemeral; all data is lost when the process is terminated
- Intended for usage with SpiceDB itself and testing application integrations
- Cannot be ran highly-available as multiple instances will not share the same in-memory data
If you need an ephemeral datastore designed for validation or testing, see the test server system in Validating and Testing
Developer Notes

- Documentation can be found here (opens in a new tab)
