+## Dynamic Operator Configuration
+
+The Kubernetes operator supports dynamic config changes through the operator
ConfigMaps. Dynamic operator configuration can be enabled by setting
`kubernetes.operator.dynamic.config.enabled` to true. Time interval for
checking dynamic config changes is specified by
`kubernetes.operator.dynamic.config.check.interval` of which default value is 5
minutes.

+2022-05-28 13:08:29,222 o.a.f.k.o.c.FlinkConfigManager [INFO ] Enabled dynamic
config updates, checking config changes every PT5M
+```
+
+For example, the default configuration of `flink-conf.yaml` in the
`defaultConfiguration` section of the Helm `values.yaml` file is as follows:
+
+```
+defaultConfiguration:
+ create: true
+ append: false
+ flink-conf.yaml: |+
+ # Flink Config Overrides
+ kubernetes.operator.reconciler.reschedule.interval: 60 s
+```
+
+When the interval for the controller to reschedule the reconcile process need
to change with 30 seconds, `kubernetes.operator.reconciler.reschedule.interval`
in the `defaultConfiguration` section can directly change to 30s:
+
+```
+defaultConfiguration:
+ create: true
+ append: false
+ flink-conf.yaml: |+
+ # Flink Config Overrides
+ kubernetes.operator.reconciler.reschedule.interval: 30 s
+```
Review Comment:
I think this is not a good example because if you try to update the
configmap through the Helm chart (using helm-upgrade) nothing will happen
because helm only checks if the configmap is present. It will not update it.
We should simply show an example of editing the configmap directly.

Review Comment:
We should say that it is enabled by default, and can be **disabled** with
the config.
