GAE bulk upload programmatically

I have a python script that is intended to run on my local machine every night. It's goal is to pull data from a third party server, do some processing on it, and execute bulk upload to GAE datastore.

My issue though is hot to run bulk upload from a python script. All examples I have seen (including Google's documentation) use command line "appcfg.py upload_data ..." and as far as I can see appcfg.py and bulkloader.py do not expose any API th开发者_StackOverflowat is guaranteed not to change.

My two options as I see them now is to either execute "appcfg.py upload_data ..." command from my python script, which seems a roundabout way of doing things. Or to directly call appcfg.py's internal methods, which means I have to recode tings in case they change.

Appengine can run cron jobs. All you need is to write is a single script which pulls the data from third party server and upload it to appengine engine, Appenigne will do the rest for you. Appengine cron this has everything you need to know about running a cron job in appengine
