In this post, we will mostly be talking about a few things that we should keep in mind while writing web APIs to get the best possible performance out of them. Most organizations work with large amounts of data that need to be processed every second. So, it's very important to keep things organized and optimized in order to deliver a great user experience. Let's discuss a few points to help you understand how we can work more of performance optimization.
Virtual Tables
If you're using MySQL or any other SQL-based database, using virtual tables is the best thing that you can do. Let's look at an example. I have three databases and in a single query I am fetching data from four different tables. This process may take some time. In that case, you can create virtual tables in your SQL databases, which are sometimes referred as views, and keep all the columns that you want to retrieve from all four tables. This time, instead of looking at all four tables, the query will pull everything into a single table. This will help to reduce the response time.
