> Create RulesEngine and RulesEngineProvider Interfaces
> -----------------------------------------------------
>
> Key: NIFI-7163
> URL: https://issues.apache.org/jira/browse/NIFI-7163
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Reporter: Yolanda M. Davis
> Assignee: Yolanda M. Davis
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> The existing RulesEngineService allows for centralized execution of rules,
> but there may be cases where processors (or other calling components) want to
> operate directly with an instance of an engine (to prevent a bottleneck with
> the controller service) or would like access to the rules driving the engine.
> To facilitate this a RulesEngine and RulesEngineProvider interface should be
> created to support the following:
> *RulesEngine:*
> Firing rules with provided facts and returning required actions
> Checking rules with provided facts and return information on which rules
> were fired from the available list
> *RulesEngineProvider:*
> Return an instance of a rules engine
