from google.appengine.api.taskqueue import Queue, Task
from google.appengine.ext import ndb
QUEUE = Queue('default')
def backend_function():
for j in xrange(800000000 / (100 * 20)):
QUEUE.add([Task(url='/remove_100_records_handler') for i in
range(20)])
def remove_100_records_handler():
for i in range(100 / 20):
ndb.delete_multi(YourDatastoreTable.query().fetch(20,
keys_only=True))
