This implies a slight change of behavior as only samples added to the respective instance of a memorySeries are returned. However, this is most likely anyway what we want. Following cases: - Server has been restarted: Given the time it takes to cleanly shutdown and start up a server, the series are now stale anyway. An improved staleness handling (still to be implemented) will be based on tracking if a given target is continuing to expose samples for a given time series. In that case, we need a full scrape cycle to decide about staleness. So again, it makes sense to consider everything stale directly after a server restart. - Series unarchived due to a read request: The series is definitely stale so we don't want to return anything anyway. - Freshly created time series or series unarchived because of a sample append: That happens because appending a sample is imminent. Before the fingerprint lock is released, the series will have received a sample, and lastSamplePair will always returned the expected value. |
