My original post was not intended to shortchange the work you and your team have done. I was just saying that when you decide to create a database or database-like application, python wouldn't have been my first choice.
In regards to your comments about development velocity and ability to refactor quickly - why are you attributing those things to Python as if it has an advantage over other languages? It seems like velocity and ease of refactoring does have some dependency on the language you are using but is more a factor of one's familiarity with the language and its tools/ecosystem. I've written lots of Python and it's no better or worse than most other languages for either velocity or ease of refactoring.
