I don't know your intended use of these ID's, my thoughts here are limited to assumed use, feel free to ignore thoughts that are off base for your use case. If, when you query for the IDs you are looking for *all* the IDs, then just serialize them into one field and retrieve them as one

I think you can do this when you pre-authorize the address you want to send the mail as. Meaning you have to log into your contactus gmail account and authorize a specific email address as authorized to send-on-behalf-of (this requires an email sent to that address to authorize the action). Of

I Can't say for Azure, but I've used the other two. AWS has SimpleDB, which is in the same ballpark as GAE's datastore, but from personal experience trying to get anything that comes close to resembling transactions from AWS SimpleDB is like taking candy from your own kid, while it's possible,

Does appengine do this in a way which is safe to a heavily-loaded application? i.e. load the new instance while the old instance is still serving requests and then simply re-direct requests to the new instance? Something like this should really be documented. From:
