> > What are the exact use cases for summing timestamps? When does it make sense? > > @Dandandan that is an excellent question. I will freely admit I was just heads down trying to get all the aggregates working rather than thinking if I _should_ be working. I can't think of any time that `sum(timestamp)` really makes sense to be honest. > > Do you think I should remove support for summing timestamps? > > As for AVG, I added a note to https://issues.apache.org/jira/browse/ARROW-12318 with your observation. 🤔 good question At least would be best to remove support for sum, as we don't have an absolute zero for timestamps. For average, I think it may make some more sense, but I think the use case seems limited to me. -- This is an automated message from the Apache Git Service.
