-JDBC have a concept of heartbeats that periodically check the health of a worker at the specified `frequency`.
+Deployments based on the [JDBC architecture](../04.architecture/index.md#architecture-with-jdbc-backend) use a concept of heartbeats that periodically check the health of a worker at the specified `frequency`.

 * If the last healthcheck is older than `heartbeat-missed * frequency * 2`, the worker will be deleted.
