This operator can be used to assure the stream order concerning the timestamps. Out of order elements are removed.

Parameter

  • debug (Boolean): If set to true, each time an element is removed, an error is print to the console.
    Remark: Printing to many debug to the console can slow down processing dramatically!
  • debugMode: Allows to define different output if an error occured.
    • 0: Minimal mode: Print only the first out of order timestamp and when processing is on order again
    • 1: Medium mode: same as 0 but print message for every out of order element
    • 2: Full-mode: Same as 1 but prints more information

Example

#PARSER PQL
#QNAME Test
#RUNQUERY
out = TIMESTAMPORDERVALIDATE({DEBUG = true, DEBUGMODE=0}, MAP({EXPRESSIONS = ['id+5']}, person))
