Hi all ES lovers, I was wondering if it is somehow possible to apply bucket aggregation to the output of a pipeline aggregation. I have the following usecase, There is a software that runs over variable amount of time and generates logs, and each run has a unique ID. Using this ID, I can figure out the start (min aggregation on Timestamp) and stop (max aggregation on Timestamp) of the software run, and thereby the duration of run can be calculated in a sibling pipeline aggregation (stop-start). After doing this, is it possible to apply a bucket aggregation on the duration, to generate a histogram for visualizing the distribution of duration ? Can such a thing be achieved using painless scripting or any other methods ? Thank you all for your reply. ---
