Thanks Roman for this Superset review, very interesting to have pro/cons about it.
If you like Python, you can try Serenytics, that’s a hosted solution (with a free plan), similar to Superset (to create dataviz without coding). It lets you write Python scripts to get data from your sources (with groupby/filters/formulas), store result of your computation in an internal storage and then use it in the dataviz. And scripts are executed directly within the platform and can be scheduled.
