clustering jforum with Terracotta

[Migrated From Jforum.net]

I work at Terracotta (http://www.terracotta.org) ? a cool open source technology that provides java clustering as a service of the runtime.

We use Jforums on our own forums and as part of a test, I clustered Jforums without changing any code by declaratively stating what needs to be clustered ?(see attachments)

Something like:
<roots>
<root>
<field-name>net.jforum.cache.DefaultCacheEngine.cache</field-name>
<root-name>theCache</root-name>
</root>
</roots>

Is anyone in the community today experiencing any pain today around JForum's existing clustering capabilities - if so please enumerate and we could see if solving the clustering problem with TerraCotta might be helpful or not. (To cluster with TC, you can download it at http://www.terracotta.org and exchange notes with me on how i set up the clustering with just config: tc-config.xml and no code changes) ...Cheers.

Wow, that's really great. I didn't know Terracotta, and is amazing to hear from you.

I have only used JBossTreeCache with JForum to allow it to run on a clustered environment (by distributing the cache among all nodes), and the problems we had at that time were only related to one or another class that wasn't serializable.

You think we can put some information about JForum + Terracotta in our Documentation page?

Yeah Terracotta clusters at the JVM level and does not employ Java serialization (so none of your classes need implement java.io.serializable to be network transportable). I didn't have to modify any code related to 2.1.6 (its the default build) to be able to cluster net.jforum.cache.DefaultCacheEngine.cache and its references, which i assumed held all of the state...

Wrt documenting it - sure - I am writing a blog and will also put together some documentation. Things are a bit hectic right now - so it might take a 3-4-few days
Cheers.

zeeiyer,
Can you send me details of how you setup cluster with terracotta? I wanna use it.

Thanks,
