[jboss-dev-forums] [Design of JBossCache] - Distributed lock manager

[manik.surtani@jboss.com]

Referencing this thread and various other discussions.

Is the subject something we want to implement in JBoss Cache in some shape or form, at some stage?

I agree that here are scalability issues with such a feature, but is it not fair comment to say that there are use cases where this is critical, our competitors have this in some shape, and it may be a good idea to offer it?

Specifically looking at a recent support case where each node in a cluster would, within the scope of a tx, read from the cache, increment the value read, and replace the value in the cache.  So a write-mostly scenario here.  And this would, when used with SYNC_REPL, inevitably deadlock after some while.

Also, two of our most high-profile competitors - Tangosol and Terracotta - both have some form of distributed locking.  Each one implemented differently, but it is there all the same.

The purpose of this thread is to discuss potential implementations and how this would work with JBoss Cache.
