Engine execution modes

Decision Server supports the RetePlus, sequential, and Fastpath execution modes. The execution mode affects which rules are executed and in which order.

RetePlus mode
Use RetePlus optimization techniques to improve performance: reduction of the number of rules and conditions, computation of the rules to execute, and prioritization of the rule order.
Sequential mode
The sequential mode executes all the eligible rules for a given rule task in sequence, which provides specific performance advantages.
Fastpath mode
Fastpath is a sequential execution mode that also detects semantic relations between rule tests in the same way as RetePlus. However, unlike RetePlus, the Fastpath mode does not support inference.
