Google app engine How do I implement an OpenID consumer in my Google App Engine project?

I want to use OpenID in my Java Google App Engine web application but I don't know where to start... I have looked at openid4java and joid. openid4java says you have to place some libraries on the "endorsed libraries"-path. I don't have one locally on my computer, and I sure don't know how to do that on Google App Engine. joid looks simple enough but doesn't look up to date or something because I get a HTTP 400 back from Google when I try to get an authentication. Any pointers?

Google app engine tiny random-looking ID generation

I'm trying to generate unique IDs for use in a Google App Engine application and would like feedback on the feasibility of the approach I'm thinking of using (questions at the end). I've read quite a few questions on this topic, but I don't remember coming across this particular approach. I'd like random-looking IDs, e.g., MD5 hashes, but I also want them to be small. Four to six characters, along the lines of tinyurl, would be ideal. The IDs will be for user-generated content, in the contex

Google app engine What's the best way to back up data on Google App Engine?

Google itself provides two solutions. http://code.google.com/appengine/docs/python/tools/uploadingdata.html One of these is new and experimental and requires you to run a separate command (and separately enter your username and password) for each kind of data you want to back up. The other requires you to twice write out information on the structure of all the kinds of your data, information that is already implicit in your models file. (We've got 25 different kinds of data so I'm sensitive

Google app engine Google AppEngine sending all requests to same instance

Lately, I have seen GAE taking much, much longer to process requests than it did just a week ago. Nothing changed in my code, but GAE now is taking 4000-12000ms to respond to requests. What makes is worse is that I have plenty of instances available with 0 requests on them. Has anyone else seen this happen? What can I do to fix it?I have gone as far as to spin up 15 extra instances (and paid through the nose for them) but nothing seems to send requests to the other idle instances reliably. My

Google app engine Bulk Download via Google App Engine Backend

I have 1.6 Million entities in a Google App Engine app that I would like to download. I tried using the built in bulkloader mechanism but found that it is terribly slow. While I can only download ~30 entities/second via the bulkloader, I can do ~500 entities/second by querying the datastore via a backend. A backend is necessary to circumvent the 60 second request limit. In addition, datastore queries can only live for up to 30 seconds so you need to break up your fetches across multiple queries
