that's one of the performance limitations with full fact replication approach for distributed pattern matching. In a situation where a significant percent of the facts always change, the most optimal method is to replicate just the indexes. Most modern RETE implementation like JESS already index the facts, so index replication allows the system to perform index joins without the fact. It's similar to how databases do index joins for partitioned tables.
I should state that I filed a patent for distributed RETE using index replication back in 2004. As far as I know, that should be the most efficient method of implementing distributed RETE and distributed reasoning. peter On Feb 20, 2008 9:12 AM, Mohd.
