[google-appengine] Instances

Hi!! We have problems with the instance feature of appengine. Today we have got 16 instances, and we've detected that many of them when receive a request, it has to start the application again. So our application consumes a lot of cpu because our startup process is a little heavy. To solve this

Re: [google-appengine] Instances

Hi Eduardo, Perhaps you could explain "we've detected that many of them when receive a request, it has to start the application again" more precisely. It is rather hard to give any advise other than make your app startup faster based on the information you've provided (for me at least). Also,

Re: [google-appengine] Instances

Hi Robert, I try to explain better: Our application has 16 instances assigned by appengine automatically and three of them are "always on". It doesn't have many requests, in fact, the time between them is large enough to appengine undeploy the application. So appengine is starting the application

Re: [google-appengine] Instances

We have a similar problem. I've disabled the app, so all instances were turned off and upon enabling it again, there were instantly 8 instances running. We're also seeing weird behavior as it seems that not all instances have the same state (which really puzzles me, since the app is stateless). I t

Re: [google-appengine] Instances

Hi Anze, Are you changing / caching things in 'local' memory or something? It is stateless in that requests may go to any instance, not the same one each time. Robert On Wed, May 4, 2011 at 02:16, Anze Cesar wrote: > We have a similar problem. I've disabled the app, so all instances were

Re: [google-appengine] Instances

No we're not storing anything in local memory. One thing that's happening constantly is we delete all entities of a given type for a user, clear the list from cache and it seems fine, but when the user refreshes, the entities are back, often for a couple of refreshes and then they're gone again.

Sounds pretty strange. You sure it is not a local browser cache or something like that? On Wed, May 4, 2011 at 13:14, Anze Cesar wrote: > Master/slave > > On Wed, May 4, 2011 at 4:44 PM, Robert Kluin wrote: >> >> High-replication datastore? >> >> >> >> >> >> >> On Wed, May 4, 2011 at 10:43

I am little confused with how these instances work. How long does an instance stay alive? A site in Python 2.5 (M/S) fires up an instance when it is accessed and the instance stays alive for minutes after. With Python 2.7(HRD) the instance is killed off after a matter of seconds. So I either have

Kate, You can set a global default cache period for all static file handlers in your app.yaml file, using 'default_expiration' as described here: http://code.google.com/appengine/docs/python/config/appconfig.html#Static_File_Handlers That should let you reduce the number of static file requests t

Hey Kenneth, The number of instances that you are billed for (and cost you free quota) can be less than the total number of instances. Look at the "Instances" graph in the "Dashboard" tab in Admin Console and you should see a green line representing billed instances - that is what you are billed

Re: [google-appengine] Instances on non-default version not shutting down after 15 minutes?

To clarify, the billed instances graph (i.e. the green line) will only be present on the default version for your app. This is because of many subtleties (e.g. the formula is per-app not per-version, the admin-console only renders graphs per version), but as long as the default version serves almos
