- Mixpanel Selecthttps://github.com/sidchilling/mixpanel_select
This is a library which can be used to select segmented data using the Mixpanel API. In my experience, oftentimes I need to extract data using the Mixpanel API on different where conditions and aggregate them. This results in boilerplate code which I have to write every time.
This library is an attempt to provide an easy way to segment data on various where conditions and aggregate them using a simple configuration map. By aggregating data, I mean that I can define a metric consisting of various events and where conditions.
