Is there any update on the following post about cache configurations?

Sorry currently none.
This is on the roadmap for 1.1. We want to implement a real two level
cache. First level will be transaction-safe and deal with given objects,
the second level only handle copies of given objects.
Is there a workable configuration for odmg at this point possibly with
compromises?
It seems that 1 and 2 are provided by the ObjectCacheDefaultImpl in the odmg
layer with pessimistic locking in a non-clustered configuration. This is the
configuration we are running now. It looks like TransactionImpl.abort
eventually calls StateOldDirty.rollback that calls removeFromCache.
Is this true?
But what about a clustered configuration with odmg?
Thanks in advance,
Mark
