Tim,
no,
nothing has been implemented yet. But we have been discussing this quite
recently, and adding such distributed cache implemenations definitely is on our
agenda for the one of the upcoming releases (0.9.9 or later). I've recently
upgraded Castor's internal Cache interface so that integration with products
like JCache or JCS will be easier.
There's already an issue out there (assigned to myself) that will
eventually add a distributed cache implementation that uses JCache internally.
But I have decided to focus on support for polymorphism and Spring integration
first, the former of which has been finished and awaits integration
into the codebase. Given the way things go with the latter, I reckon that I'll
be able to start working on such a cache implementation right after the 0.9.7
release in two weeks time
Other than that, if you had some spare time (or some ready code .. ;-)),
we'd really appreciate your contributions.
Regards
Werner

Betreff: [castor-dev] Distributed Castor JDO Cache
To whom it may concern,
has anybody implemented a pluggable distributed (synchronized) cache for Castor JDO based on JCache (or a related distributed caching API) ?
Bruce Snyder refers to the intention of using JCache in comments at "http://hypermail.linklord.com/castor-dev/2004/Jul/4697.html". Bruce's comments are in response to a query about distributed caches by Kalpesh Patel.
We are looking at the problem of synchronizing multiple Castor JDO caches across multiple application servers on different hosts.
A simple approach may be to notify listening Caches when the TxSynchronizable#commit method is invoked. JMS is a safer transport mechanism, but TCP is also a contender.
Comments welcome.
Tim.
