Hi T.J., I'm glad you've raised this issue. The documentation on quotas has most of this information:
http://code.google.com/appengine/docs/quotas.html For additional limitations, most overview sections on the APIs and services have specific details for that service. For example, see: http://code.google.com/appengine/docs/java/datastore/overview.html#Quotas_and_Limits http://code.google.com/appengine/docs/python/images/overview.html#Quotas_and_Limits http://code.google.com/appengine/docs/java/mail/overview.html#Quotas_and_Limits The limit on 100 custom composite indicies per app is not currently documented to my knowledge, part of the reason is that I think it would be best to design your app without that constraint in mind. So far, very few apps have hit this limit and if you need more than 100 indicies, I'd be happy to talk it over and see what we can work out. Recent reports of hitting this limit have been the result of an issue which caused the number of indicies to be overreported for a small subset of apps.
