I've been monitoring my app today for cost and the instances are so far fairly ok. However I'm getting absolutely hammered on the datastore operations. (yes, this was in the billing preview)
I found this gem with seems to have been updated since I last looked at it. This may be old news to people but I just discovered it. http://code.google.com/appengine/kb/postpreviewpricing.html#operations_charged_for I was under the impression that if you did an entity get by key it was a small operation, apparently not. If you put a new entity with 4 indexed properties that's actually 10 writes! If you update those 4 properties 18 writes! If you delete that entity 10 writes again! If you have a composite index you're screwed even more. I understand how the datastore works and all but that's pretty crazy. Every time I look at a property and think maybe I won't index that one I think actually no, I can see how I might need that sometime.
