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