Memory error in GAE python
I bulkloaded to the data store 88 entities, each one is composed from a unicode field (name), and a list field (lst) of 4996 numbers. The bulk loader section of the list looks like this:
property: lst
external_name: lst
Type: List
import_transform: "lambda x:x.split()"
After the import I could see in the data store view开发者_JAVA技巧er all the entities. When I try to run this code:
def an(x):
return x.name
class Name(db.Model):
name=db.StringProperty(unicode)
lst=db.ListProperty(int)
class Calc(webapp.RequestHandler):
def get(self):
begin=Name.all()
self.response.out.write('<html><body>')
self.response.out.write(" ".join(map(an,begin)))
self.response.out.write('</body></html>')
I got a memory error. When I erased most of the entities from the data store, and only few left it worked OK. I added few more and I got memory error again.
Do I have to import csv files with 10 entities each, or can I import any number of entities in the file?
what did I do wrong anyway?I'm a newbie in GAE, so please be patient. Any help will be appreciated.
