I like to think of GAE as a relational database without JOINS and
without transactions.
With this limitations and a few caveats the the same web2py APIs that
work for relational databases work on GAE.
1) you connect with
from gluon.contrib.gql import *
db=GQLDB()
2) the id is still there but it is an int uuid, not an autoincrement.
This is not a problem since we never use the fact that it is an
autoincrement
3) you cannot mix queries involving the id and involving other fields.
4) no joins
5) no OR
7) no LIKE
8) no nested selects
9) no transactions
10) no more than 1000 records at the time
These are all GAE limitations, not web2py limitations.
