Subject Re: Changing CA configurations under Python
Date Sat, 20 Mar 2021 17:58:05 GMT
Right. It’s more or less the same issue though as I need to actually change the CA file in
use after the program starts by setting the env. The correct file to use is listed in a large
config file that needs to be parsed.

I’ll file an issue.

like these can only be set once when the pyarrow.fs module is loaded. Is it possible to modify
these values after the initialization has occurred? It’s fine that they are global, I just
have to load a Certificate file at a later point.
