Herman Kolstad Jakobsen commented on KAFKA-7699: ------------------------------------------------ Working with real-time data from the power grid, this feature is really sought for! Our use case is that data should be delivered at given intervals and at a given time within that interval. For instance, data should be delivered every 10 seconds and at second 7 within that interval, e.g. 09:00:07, 09:00:17, etc. > Improve wall-clock time punctuations > ------------------------------------ > > Key: KAFKA-7699 > URL: https://issues.apache.org/jira/browse/KAFKA-7699 > Project: Kafka > Issue Type: New Feature > Components: streams > Reporter: Matthias J. Sax > Priority: Major > Labels: needs-kip > > Currently, wall-clock time punctuation allow to schedule periodic call backs > based on wall-clock time progress. The punctuation time starts, when the > punctuation is scheduled, thus, it's non-deterministic what is desired for > many use cases (I want a call-back in 5 minutes from "now"). > It would be a nice improvement, to allow users to "anchor" wall-clock > punctation, too, similar to a cron job: Thus, a punctuation would be > triggered at "fixed" times like the beginning of the next hour, independent > when the punctuation was registered. -- This message was sent by Atlassian Jira (v8.20.10#820010)
