    Description

      Motivation: a DMN decision table can be evaluated faster than naive algorithm by translating it into a Rete/Phreak, but the current kie7 approach is suffering from performance bottleneck artificially induced by use of kie7 rule units, which provide more harm than benefit to perfomance (performance is actually worst for most "realistic" cases).
      Goals: a POC to understand what’s need to be done to support the alpha network compiler (wihout kie7 rule units) in DMN. We currently estimate it will take us 1 to 2 summer sprints and the output will be more epics to implement this feature.
      Impact: alpha network compiler code refactors for the better use of.

      One part of the POC was to hard-code the alpha network for a specific table (DROOLS-4566) the remained of the poc is to generalize the approach further to fully assess the impacts thanks to the poc.

          Bug - A problem that impairs or prevents the functions of the product. DROOLS-5925 Partitioned Alpha Network Compiler

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
