memcache | go language memcached client

You have to provide created_at and updated_at values to time format otherwise you should update automatically when ever the data is created into that particular table.

You provide following line into the specific model

Add this to your .htaccess file

I don't know why, but the way I restarted my server during deploy doesn't refresh env.ini, and the server remembers the old settings. If I restart my server with sudo reboot, with the same settings, then CACHES is equal to {'default': {'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache', 'LOCATION': '127.0.0.1:11211'}} and the site works properly. And I confirmed that if I put dummy values in env.ini then the site doesn't work at all. But only if I restart my server with sudo reboot.

This syntax is obsolete:

If you are using docker, you don't have to use any host as localhost, but rather use the service name as the host, for example, if you docker-compose.yaml is like this:

You can imagine different solution to solve your issue.

1. You can embed your models in your deployment. Like that, the model are already here with the service. When a new model version is released, you deployed a new app engine service revision
2. The problem with the precedent solution is the deployment frequency: when one of the model is updated you need to repackage and redeploy your App Engine service. The solution is the micro services. You can have 1 model per APp Engine service and therefore only deploy this one that has been updated. If you want only entry point, you can have a 26th app engine service wich is your entry point and will route the request to the correct model service.
3. You can also perform the same thing with Cloud Run, where you manage the container packaging and detail if you need special things. You have also more flexibility on the number of CPUs and the memory size.

Last point, after solving the download issue part, you could have cold start issue: the time that take your server to start and to load in memory your model (at the first request, when the instance start). Cloud Run proposes a min-instance feature to keep warm a certain number of instances and therefore to eliminate the cold start issue.

If we're talking about in-process memory, then a static field will have exactly the same lifetime as anything in MemoryCache.Default, but the field will be more direct, and therefore faster. The bigger problem, however, is the race condition if you ever mutate the contents of the list after it has been assigned, since multiple threads could be looking at the data at the same time (bad things). It is probably a good idea to use some kind of immutable collection (ImmutableList, for example), to avoid any complications there.

If you set the ttl correctly in memchache, it won't return the value after the expire time. So, there is no need to delete it since there is nothing there to delete! I don't know your code's exact logic but this should work:

1. You've configured your cache backend to use a Memcached server at 127.0.0.1:8000. That's likely a misconfiguration, since your Django development server would run at 127.0.0.1:8000 by default. The default port for Memcached is 11211 – you might want 127.0.0.1:11211.
2. Have you downloaded Memcached and started it? Are you sure there's a Memcached instance listening?
