Hi! I have a simple image-server.py with the following code:
import cgi import logging from google.appengine.ext import db from google.appengine.ext import webapp from google.appengine.ext.webapp.util import run_wsgi_app from google.appengine.api import memcache class Image(webapp.RequestHandler): def get(self): if self.request.get("key") != "": key = self.request.get("key") data = memcache.get(key) if data is not None: if data.image: self.response.headers['Content-Type'] = "image/ png" #self.response.headers['Cache-Control'] = "public,max- age=31104000" self.response.out.write(data.image[0].image) logging.debug("Served from memcache") else: self.response.out.write("No image") else: data = db.get(key) if data.image: self.response.headers['Content-Type'] = "image/png" #self.response.headers['Cache-Control'] = "public,max- age=31104000" self.response.out.write(data.image[0].image) logging.debug("Served from datastore") else: self.response.out.write("No image") if not memcache.add(key, data): logging.debug("Memcached failed!!!!!!!") else: self.response.out.write("No image") application = webapp.WSGIApplication([ ('/download', Image) ], debug=True) def main(): run_wsgi_app(application) if __name__ == '__main__': main() I did a test and served 1000 images after they have all been cached in memcache. The Admin Logs show that all requests are "Served from memcache". However, when I check the Quota Details in the Admin, I noticed that for every request, not only the quota details for Memcache API Calls, but Datastore API Calls are also incremented. Memcache quota displayed 1000 while datastore quota displayed exactly 2000 API calls. And the ratio is for every 1 memcache API call, 2 datastore API Calls are called. I have no idea, why this is so. Please, someone enlighten me. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
