/**
* @since {@link RemoteApiVersion#VERSION_1_24}
* The version number of the object such as node, service, etc. This is needed to avoid conflicting writes.
* The client must send the version number along with the modified specification when updating these objects.
* This approach ensures safe concurrency and determinism in that the change on the object may not be applied
* if the version number has changed from the last read. In other words, if two update requests specify the
* same base version, only one of the requests can succeed. As a result, two separate update requests that
* happen at the same time will not unintentionally overwrite each other.
