Support reading SAV files from memory

[janwillemvl]

As far as I can see, currently the read_sav function only supports reading in a file from local drive. My script does not have writing rights on local drive, and the idea is that it reads a sav file from S3, parses it and writes the parsed contents to a RDS database in AWS. This would work if the function read_sav would accept an in-memory-file (BytesIO object).

Yes, I agree it would be very useful. Unfortunately it is not possible at the moment as the underlying C library Readstat does not allow that.A PR has already submitted but has not progressed so far. You can read more details here:

Thanks for the quick reply. From the looks of it, some integration tests failed and nobody has picked it up for over a year. So probably nobody will pick it up, unfortunately. I don't think I can do anything to help, right? I'll look for an alternative to reading from memory like using a temporary file storage mounted in the docker container we use.

Yes, it probably will take a long time before it is solved, if it gets solved at all. So you need to arrange some alternative for your work if you want to progress

Ok, thanks for your support anyway!
