Hi,
I was just working on updating the aggregation pipeline element in flink to support nary-mappings, when I stumbled upon this. Currently, we show the timestamp fields as potential mapping properties in the user dialog as suitable candidates, e.g. to perform aggregation such as calculating an average. I guess, it make sense to exclude the timestamp field(s) from the list of mapping properties, such that timestamps are not shown to the user - if not necessarily be required by the pipeline element. What do you think? Cheers, Patrick
