Annotation Interface CommandLock

@Target(TYPE) @Retention(RUNTIME) @Documented public @interface CommandLock
Annotation used to indicate what type of lock to acquire before executing an admin command. By default (witout this annotation), admin commands acquire a shared lock, allowing multiple admin commands to execute in parallel. Some commands, such as the synchronization command and the quiesce command require the exclusive lock to prevent any other admin commands from executing. Admin commands that are "read-only" and don't change any configuration state don't need any lock.
