Hi Google has surprised many with massive change in pricing and
specially the way it is now calculated.
It is available at
http://www.google.com/enterprise/cloud/appengine/pricing.html
I have 2 questions on it
1)Meaning of "small ops"
2) How cost of GQL query or fetch() will be calculated, will it vary
with number of results.
Following is a snippet from the New pricing page.
Datastore API
$0.01/10k write ops $0.07/10k read ops $0.01/100k small ops
