Right now at my current employer "we" are about to embark on replacing our entire data pipeline with a very popular queuing system designed to process hundreds of GB or more of data per day. Our current pipeline moves a few tens to hundreds of MB per day (not second, minute or hour) from the point of intake to our internal data stores. There are two reasons as I see it for the choice: resume driven development by the "architect" who proposed it (and management who want to put the management portion on their resumes) and laziness to address other issues regarding why there are delays at certain points in the pipe.
