# Redis

Sourcebot uses Redis as a job queue for background indexing work.

## TLS

To enable TLS for your Redis connection, set `REDIS_TLS_ENABLED=true`. You can also enable TLS implicitly by using a `rediss://` connection string in `REDIS_URL`.

| Variable                          | Default | Description                                                                                                                          |
| :-------------------------------- | :------ | :----------------------------------------------------------------------------------------------------------------------------------- |
| `REDIS_TLS_ENABLED`               | `false` | Enable TLS for the Redis connection. Alternatively, enable tls via `rediss://` connection string.                                    |
| `REDIS_TLS_CA_PATH`               | -       | Path to the CA certificate for the Redis connection.                                                                                 |
| `REDIS_TLS_CERT_PATH`             | -       | Path to the certificate for the Redis connection.                                                                                    |
| `REDIS_TLS_KEY_PATH`              | -       | Path to the private key for the Redis connection.                                                                                    |
| `REDIS_TLS_KEY_PASSPHRASE`        | -       | Passphrase for encrypted private keys. Required if your TLS private key is password-protected.                                       |
| `REDIS_TLS_SERVERNAME`            | -       | Server name for SNI (Server Name Indication). Useful when connecting to Redis through a proxy or with custom certificates.           |
| `REDIS_TLS_REJECT_UNAUTHORIZED`   | `true`  | Set to `false` to disable certificate validation. Not recommended for production. When not set, defaults to Node.js secure behavior. |
| `REDIS_TLS_CHECK_SERVER_IDENTITY` | -       | Set to `false` to bypass server identity checking. Use with caution in enterprise environments with custom certificate setups.       |
| `REDIS_TLS_SECURE_PROTOCOL`       | -       | TLS protocol version (e.g., `TLSv1_2_method`, `TLSv1_3_method`). Uses Node.js defaults when not set.                                 |
| `REDIS_TLS_CIPHERS`               | -       | Custom cipher suite configuration. Allows specification of allowed TLS ciphers for enhanced security requirements.                   |
| `REDIS_TLS_HONOR_CIPHER_ORDER`    | -       | Set to `true` to use server’s cipher order preference instead of client’s. Useful for enforcing security policies.                   |
