Datastore puts not working

[Kyle Baley]

We've been having an issue for the last hour with puts not working. When I save something, everything appears to succeed and there are no errors in the log but when I refresh the page, the previous changes I made disappear. This is happening in two different applications we have (the same codebase but one for staging and one for prod) but not in the third. The AppEngine status is showing green and I haven't received any emails indicating the team is looking into any issues which is why I'm posting here. We haven't hit our quota and haven't updated our app in over a week.

Never mind! The email from the AppEngine team just came in.

I'm having the same issue. Have not received an email yet - are they looking into it?

Sometimes my puts work but the queries are returning zero results for certain kinds. We've made zero code changes in 5 days, so it's def. a datastore issue with certain indexes not being updated.

Here's the email I got:

We're investigating an issue with Google App Engine Datastore beginning at Tuesday, 2014-03-18 11:45 AM. We will provide more information shortly.

Looks like it's an extreme case of 'eventual consistency'. Theoretically those results are all saved but your queries are just not returning them because they are hitting a node where the data hasn't written to the index. It's been many hours now and I still don't see them showing up, so I have my doubts they will ever 'eventually become consistent'. I'm monitoring to see if I start seeing them pop up at any point.
