I was wondering, what about if I use db.create_rpc(deadline=1)
Will I be charged if the deadline is reached, and I get nothing from

Thanks

folks-- gmail is now flagging all non-DKIM-signed email as possible
phishing, which is destroying the value of the App Engine Email API.
what's the ETA to add DKIM support? (and why is this lower priority than,
say, Prospective Search?)

Hi
I have a question about migration of existing apps into the new pricing
structure...
We have numerous (50+) apps running across 3 different apps for domains
(appspot.com + 2 of our own). Although we have our own apps for domains, all
apps have an *.appspot.com url.
This came about as we st
I'll agree that sometimes it's hard to understand priorities, say for
instance XMPP in general, or yes, prospective search.
All that aside, I'd encourage everyone to check out using Amazon's SES
service to send email via GAE. Their REST api works well and I
actually get fewer urlfetch timeouts usi

Hello All,
I'm trying to figure out a clean way to make my Expando model's
searchable. I will have many user-defined fields that will need to be
more or less searchable. This means that I would have to "normalize"
my data (such as lower case all fields) so that the search is case
insensitive.

This is the stupidest thing anyone has said to m
+1 on the Amazon SES suggestion. I would rather the App Engine team focus
on other priorities than mail, imho. Just DKIM is only part of the solution
needed for getting mail deliverability humming... Then Sendgrid, Mailgun or
something when you have a bit more volume or want more stats etc.

Actually, seems like emails are needed when logging in using a Google
apps account. ie not a gmail address account.
Not sure, its hard to debug here, I don't have access here to a lot of
different account types to try.

I don't believe you'll need to do anything when we ship concurrent requests
for Python, as long as you're not using global mutable state anywhere. It's
unlikely your threads will ever need to talk to each other.
