Hey, we are using eKuiper with EdgeX to sort (asc) incoming values with a simple rule.
RULE:
It sorts correctly if the tumbling window is set to 30 (seconds), but we realized that if we change the tumbling window to 60 (seconds) the sorted results differ. So, the Kuiper rule doesn’t sort (asc) entries according to the rule set and the observed order is non-deterministic.
Result with Tumbling Window set to 30 seconds (RESULT OKAY):
Result with Tumbling Window set to 60 seconds (RESULT NOT OKAY):
The event of the format which we are receiving and working with is coming fron an opcua source:
How come the tumbling windows affects the sorting of the values as seen in the example given above?
Do you guys have any idea about this issue or have seen any documentation? I haven’t found anything yet …
Appreciate your time and your effort in advance. Thanks !!
