Has anyone used Table.Partition() in a dataflow or report? I am looking for a use case that demos any performance improvement from using this M function. I can't find anyone utilizing it in an online discussion or video.
That use case seems particularly weak. The comment theread is more interesting though. I gues I'm trying to understand whether there are certain merges or functions that perform better when the data is partitioned and operations are run in parallel.
In my mind, it doesn't seem that different from Group By using the All Rows aggregation. So I wouldn't really expect it to unlock unique performance gains compared to that more-common operation.
Chris Webb suggests creating histograms as a potential use case.
