Feature Request

The impressive datashader python package (easier to install with conda) allows real-time visualisation of billions of rows of in memory pandas/numpy data (it uses numba JIT-ted optimised rasterisation routines), it's conceivable that it could be integrated with superset since superset nicely manages expensive query operations through celery tasks.

Here's a demonstration video of datashader https://www.youtube.com/watch?v=6m3CFbKmK_c

Superset does the visualization part in js on the client so not sure that datashader will fit in the picture.

If you were to consider it as a new back-end it would work, sending the front-end static renders, it's a big feature I'll admit, but for 2+ years from now you could find it very valuable, it would then compete with mapD https://www.mapd.com/demos/
