Node.js is a tool for building fast network applications. But in the past couple of years, JavaScript has started to play a larger role outside of the browser, due in large part to Node.js. Because it’s built into most web browsers, programmers and web designers can use JavaScript to add interactive features to websites that reach billions of people. JavaScript is one of the most popular programming languages in the world.

Try our program out with a free seven-day trial today. Now, all we have to do is set the backend in our cache preference and set the location of the database table.If you’re looking to take your JavaScript coding to another level, Treehouse offers unlimited-access courses in JavaScript (and many other subjects) starting at $25/month. This will make the table as per the expected configuration of your django app. To set it up all we have to do is create the cache database table as given below: $ python manage.py createcachetable This works swimmingly if we have a well-indexed database. Caching Databaseĭjango provides us with the availability of saving the cached data to our database. Let’s tackle all the levels of cache granularity that django provides us. All we have to do is define what type of caching do we want to integrate in our settings.py (or common.py in Charcha), how long will it live for and where it can be stored. Setting up cache in django is exceedingly easy. We have already introduced some cache which has already been mentioned in our one of our posts. Let’s try dividing all the cache that could be used as per the aforementioned levels of cache granularity.ĭo note that Charcha might not really require cache at all if the maintenance might be high. We would tackle the advantages and disadvantages of the caches as well. In this blog, we would discuss which cache system is best suited for us. It provides you with different levels of cache granularity. Now, this all sounds pretty much on the upside but caching does have a lot of drawbacks.ĭjango already comes with a cache system where it lets you save the pages but that’s not it, Django does much more than that.

What caching would be doing is, it would be removing the burden of you having to do the queries, again and again, rather it would just store the result and send it directly to the client.

We can all agree that for high traffic sites the overhead can be pretty overwhelming. For a high traffic website, you would basically be asking your server to handle X number of requests, making it perform N number of queries to generate some ‘y’ number of templates. Now, this is just a simple example using Charcha, if we go higher we might find that these sort of cases are really common. According to this logic, your server would have to make separate queries to the database and generate different templates based on your authorization (let’s just say permissions from now onwards). Now let’s say a new user comes along and all he/she is authorized to do is see the blog and the top comment. Let’s take an example to better explain this, let’s say you are an admin of Charcha and you are authorized to see all the comments and votes given to all the blogs. The challenges that most sites face is that they have to serve multiple clients and for an obvious reason your application might have to show different data or templates to different clients based on your use-case. Why is this required?Ĭaching is one of the most useful techniques used by developers to improve the performance of their application.

The source code for the C harcha forum is available here. The inspiration of this post has mainly been, to introduce a caching mechanism inĬharcha Discussion Forum.

In this post, we will go through how to assess which cache can be used and how to use it.
