Subject: Re: [Hibernate] JCS cache -
Distributable read-write
Nice diagram! I wish the Hibernate doco had some
diagrams like that....
What I mean by "transactional access" is we would
have to be able to read a value out of the cache, check its timestamp, and
then put a new value in the cache as an atomic operation. Currently we do this
by synchronizing on the strategy object. That approach won't work for a
distributed cache. I detailed an approach that would work (a remote
LockServer) in a previous email. If you read that carefully you will see
exactly how isolation would be broken without
it.
