I need to restrict access to the TreeCache in our cluster to ensure that no two updates will occur on the same node at the same time. Is there a mechinism in TreeCacheAOP that handles this? Or would I have to develop my own locking mechanism from JGroups using a class like DistributedLockManager?
If the mutual updates upon timeout from conflict scenario that we currently having does not meet your requirement, then yes, you will need to provide one of your own. We don't have plan to provide DistributedLockManager yet.
