Streaming aggregation relies on knowing the problem beforehand, so it's pointless in the context of the day-to-day work of analysts where most of the project is spent figuring out the right questions to ask. If I need to stream data because the size of data is a constraint, I'm either working on the 0.1% of projects that require it or on an analytical product rather than an analytical project.
