### Read replicas
Additional databases used only for read operations can be configured. Increase the number (by default `0`) in the following configuration settings for each read replica.
You can configure additional read replica databases that are used only for read operations. To configure authentik to use replicas, add the settings below to your [configuration file](./configuration.mdx#set-your-environment-variables). If you have multiple replicas, add additional settings for each replica, replacing the default `0` with a unique value for each additional replica.
If read replicas are configured, the main database is not used for reads. If you'd like the main database to be included for reads, add it as a read replica.

The same PostgreSQL settings as described above are used for each read replica.
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__HOST`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__NAME`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__USER`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__PORT`

- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__SSLCERT`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__SSLKEY`
Note that `USE_PGBOUNCER` and `USE_PGPOOL` are inherited from the main database configuration and are _not_ overridable on read replicas.
