[jira] [Created] (UNOMI-163) Optimize PropertyConditionEvaluator

Serge Huber created UNOMI-163:
---------------------------------

             Summary: Optimize PropertyConditionEvaluator
                 Key: UNOMI-163
                 URL: https://issues.apache.org/jira/browse/UNOMI-163
             Project: Apache Unomi
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.3.0-incubating
            Reporter: Serge Huber
            Assignee: Serge Huber
             Fix For: 1.3.0-incubating


The current implementation of this evaluator uses OGNL expression to resolve property values. While this is very flexible it also comes with a performance cost. 

This is a problem as in high load scenarios this evaluator is called a lot (millions of times actually), so the idea is to provide some optimizations by hardcoding some of the expressions to make them faster.
