-- `cluster.persistent_tasks.allocation.recheck_interval` (Time unit): The cluster manager automatically checks whether persistent tasks need to be assigned when the cluster state changes in a significant way. There are other factors, such as memory usage, that will affect whether persistent tasks are assigned to nodes but do not otherwise cause the cluster state to change. This setting defines how often assignment checks are performed in response to these factors. Default is `30 seconds`, with a minimum of `10 seconds` being required.

+OpenSearch supports the following cluster-level coordination settings. All settings in this list are dynamic:
+
+- `cluster.fault_detection.leader_check.timeout` (Time unit): The amount of time a node waits for a response from the elected cluster manager during a leader check before deeming the check a failure. Valid values are from `1ms` to `60s`, inclusive. Default is `10s`. Changing this setting to a value other than the default can result in an unstable cluster.

+- `cluster.fault_detection.follower_check.timeout` (Time unit): The amount of time the elected cluster manager waits for a response during a follower check before deeming the check a failure. Valid values are from `1ms` to `60s`, inclusive. Default is `10s`. Changing this setting to a value other than the default can result in an unstable cluster.
