How to fetch more than 1000?

Question

How can I fetch more than 1000 record from data store and put all in one single list to pass to django?

Answer 1

This is close to the solution provided by Gabriel, but doesn't fetch the results it just counts them:

count = 0
q = YourEntityClass.all().filter('myval = ', 2)
countBatch = q.count()
while countBatch > 0:
    count += countBatch
    countBatch = q.with_cursor(q.cursor()).count()

logging.info('Count=%d' % count)

Works perfectly for my queries, and fast too (1.1 seconds to count 67,000 entities)

Note that the query must not be an inequality filter or a set or the cursor will not work and you'll get this exception:

AssertionError: No cursor available for a MultiQuery (queries using "IN" or "!=" operators)
