Valkey is an open-source, Redis-compatible key-value store used in Themelio for session management. It stores impersonation tokens mapped to session IDs, enabling the backend to retrieve GitLab credentials during authenticated requests. Sessions are created during sign-in and cleaned up during sign-out.
