Official Julia implementation of Apache Arrow
The Arrow dictionary format allows for an `ordered` flag indicating that the order of the elements in the dictionary should be preserved. This corresponds to the `ordered` property of a...
In Julia, there is (generally) a useful/meaningful semantic distinction between `nothing` and `missing`. IIUC, Arrow doesn't really have equivalent values that capture this distinction, but instead has `null` which might...

Hi @quinnj , thank you for just willing to consider this wild attempt! The only pkg you need to re-create is PyArrow and [awkward-1.0](https://github.com/scikit-hep/awkward-1.0) on the python side and PyCall.jl...
