[GitHub] [streampipes] dominikriemer opened a new issue, #589: Processing Element: Detect Value Change

dominikriemer opened a new issue, #589:
URL: https://github.com/apache/streampipes/issues/589

   The processing element should be able to detect when a numeric property change from one configured value to another (example: result=0 -\> result=5).
   ### Required Input
    * A numeric value
   
   ### Configuration
    * Value of last event (example: 0)
    * Value of current event (example: 5)
   
   ### Output 
    *  Append Strategy (changeDetected: Boolean)
   
   ### Module
    * streampipes-processors-enrich-jvm
   
   We have a new API for processors, so we only need one class (see:  [1] for an example)
   
   PS.: There could also be more configurations to make the processor more generic
