I’ll confess to ‘scary’. 
I’m trying to do a sqlite virtual table entirely in numba, currently using this inside the jit-func in order to get the address. It’s effectively a re-ask of a gitter thread (thanks @stuartarchibald for the tip on how to get the link)(hover over the post time to show it)
It seems be going fairly well… this question is also in support of my quest.
The devil is always in the details, but this feels like a perfect application for numba- native performance virtual tables presenting numpy structures to the sql interface. If it works.
