DiggidyDave commented on issue #9190: [SIP-39] Global Async Query Support URL: https://github.com/apache/incubator-superset/issues/9190#issuecomment-590609298 The bulk polling could make sense to reduce load, but my bigger point here is that scaling a fleet of HTTP servers (or even routing a particular endpoint to a distinct dedicated fleet) is a pretty simple problem that can be accomodated in most environments, whereas websockets and sidecars have a lot of interesting problems in that area and may not even be feasible in some environments. For the last point, that sounds like a front-end bug, not a problem inherent with small HTTP GET requests for short polling. Polling is much simpler in terms of the tech involved (and can be stateless), so I am skeptical that small front-end bugs will cease to be a problem if we adopt a more complicated technology to replace the foundation. And to be clear, I'm not meaning to dismiss the idea of websockets, I just want to make sure that the simpler alternative is discussed and the trade-offs. It also might be worth discussing the relative strength of the "cons" for SSE. "Some browsers" don't support it, which means the subset of the IE11 users (1.55% globally) that is not on Windows 10, as well as Opera.
