Bryan Rosander updated NIFI-3235:
---------------------------------
Description:
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- recycling JsonPath objects
from a queue 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.
