I get sensor data every 10 seconds. When using aggregateWindow as shown below, I would have expected the “_time” field to stay the same over the 10 seconds period until the new data is available, however, if I submit the same query multiple times within this 10 seconds window, the “_time” field sometimes changes to some unexpected odd numbers and on the next query it is back to normal. Why?
from(bucket: "sensor")
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r["_field"] == "255/0/0")
|> aggregateWindow(every: v.windowPeriod, fn: median, createEmpty: false)
How _time is expected:
How _time looks on some queries:
