Hello,

I’m working on a project that needs a high performance rules system for processing batches of objects. Typically I’ll have a dozen or so rules, the most complex of which will aggregate several objects based on timestamps and specified data patterns. The objects will come in batches of a few 100ks. The system is reset back to the starting point after each batch is processed.

My guess at doing this with Drools is that you load up all the rules and enter all the objects as “facts”. You then hit fireallrules and sit back and wait. Doing this, I only get so much performance and I can see that its only using a single thread. Is there a way to process the whole lot in a parallel, or multithreaded way? Unfortunately there's no natural way to partition the objects that would make things easier.

Cheers,

Tim
