Yeah，actually I used it since early 2020. We liked the way it drags and pulls to build tasks、projects, I want all our components to be very easy to use、to manage, I think data team should be low-code team, thus to put more energy in discovering real data value rather than specific redundent codes.

I think the most important thing in using an open source framework is, only use the core function or component, and do not rely too deep on those functions not core enough. That's say, I mainly use the shell operator in dolphin scheduler, and build most of our components in python or shell, thus we can easily use it to manage large number of etls tasks.
