Jeff, Oh, I misunderstood you the first time. But yes, as usual you are right! That is how it was designed to be. Regarding comments, the use of entry points for events is highly recommended because it reduces the matching space for the events and allows for concurrent feeding of data into the engine. End result is better performance and scalability, as you mentioned already. On top of that, data transformation is also a possibility adding flexibility. As of Drools 5, we don't support distributed working memory. In case the business case allows for any kind of data partitioning (you know, like sending all customers whose name starts with "A" to one server and "B" to the other server", then it is a good strategy, because it also helps reducing the match space. Of course, the same knowledgebase can be replicated to all servers and sessions instantiated in each of them.
