[jira] [Created] (NIFI-3235) EvaluateJsonPath performance improvements

Bryan Rosander created NIFI-3235:
------------------------------------

             Summary: EvaluateJsonPath performance improvements
                 Key: NIFI-3235
                 URL: https://issues.apache.org/jira/browse/NIFI-3235
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Bryan Rosander
            Priority: Minor


EvaluateJsonPath does a lot of work in every onTrigger() that can be done when scheduled.  This has the effect of making it take more cpu cycles than necessary to do its job.

Initializing the JsonPath objects in a ThreadLocal because they aren't thread-safe and getting the properties from the ProcessContext a single time in onSchedule() should reduce the amount of CPU time this processor needs to perform a given task.
