+## JDBC Healthcheck
+
+JDBC have a healthcheck that will check every worker at every `frequency`.
+
+* If the last healthcheck is older than `heartbeat-missed * frequency`, the worker will be marked as unhealthy.
+* If the last healthcheck is older than `heartbeat-missed * frequency * 2`, the worker will be deleted.
+
+If a worker is still running after being deleted, it will stop itself.
+
+### `kestra.heartbeat.frequency`: Check frequency, in duration
+
+Default value is `10s` or every 10 seconds.
+
+### `kestra.heartbeat.heartbeat-missed`: Missed heartbeat allowed
+
+Default value is `3` or 3 missed heartbeats allowed.
