 OpenSearch supports the following system settings:
 
-- `cluster.name` (Static, string): The cluster name. 
+- `cluster.name` (Static, string): The cluster name. Default is `opensearch`.
 
-- `node.name` (Static, string): A descriptive name for the node.
+- `node.name` (Static, string): A descriptive name for the node. Required.
 
-- `node.roles` (Static, list): Defines one or more roles for an OpenSearch node. Valid values are `cluster_manager`, `data`, `ingest`, `search`, `ml`, `remote_cluster_client`, and `coordinating_only`.

-- `bootstrap.memory_lock` (Static, Boolean): Locks the memory at startup. We recommend setting the heap size to about half the memory available on the system and that the owner of the process is allowed to use this limit. OpenSearch doesn't perform well when the system is swapping the memory.
