问题 I'm trying to work out of I can take advantage of a caching layer in my web application or not (and if so which technology). Our web app has and internal and external component and I would like if possible to add an in-memory cache tier between the Web App and DB Tier for the public external component.

问题 Issue: I am working on a kind of e-commerce platform which has sellers and buyers.Now in my case a seller can also be a buyer i.e every user can buy plus sell. So i have a single table called users .Now I want to implement a follow vendor/user feature,wherein the user can click follow and he sees all the goods listed by that vendor under his account(till he unfollows). Now my traditional approach was to have a table that has a key and two columns to store the follower and the followed Eg: |id

How do I store a fetched entity in memcache for App Engine?

由 心已入冬 提交于 2019-12-11 21:08:04
问题 Because each new request in App Engine creates a new Handler, the entity I'd like to alter and put (using POST) has to be retrieved again. This seems wasteful, since I've populated the form with the information from GET a moment earlier. How do I store a key, fetched entity, or key/entity pair in memcache for App Engine? 回答1: From here: def get_data(): data = memcache.get("key") if data is not None: return data else: data = self.query_for_data() memcache.add("key", data, 60) return data

Unable to get Enyim.Caching MemcachedClient to work with Couchbase

由 不问归期 提交于 2019-12-11 19:27:51
问题 I realize that Couchbase provides a client to their memcached server, but I'm trying to get the enyim.caching client to work. Here's my trivial c# code that uses the Couchbase client (which works) and then pretty much the same thing with the enyim MemcachedClient: class Program { static void Main(string[] args) { var client = new CouchbaseClient(); client.Store(StoreMode.Set, "somekey", "somevalue"); var somevalue = client.Get<string>("somekey"); Console.WriteLine(somevalue); Console.ReadLine
