![]() If all requests hit the same database using a long running connection, it won’t make a difference if the calls are asynchronous or synchronous. ![]() In addition, another situation when async may not be useful is when you have a single database server not utilizing connection pooling. ![]() ![]() There’s no real performance benefits to using async for these calculations. One case I feel programmers may overly use async is for simple and basic computations. “Asynchronous programming and parallel programming have great benefits…”īut can be overly used at times. In other instances, though, it’s cliché and often to the detriment of the users’ device to utilize async so heavily. There are work-arounds, and async is necessary in instances such as preloading data when the app first begins. The amount of resources used at this time is much higher than normal app usage and ultimately, with lots of refreshes, users’ memory suffers. All of the fancy gestures that are usually present in applications happen because of async calls to the services at the same time as entertaining the user with some logo or messaging. Literally speaking, when an application asks for data (from a database, webservice, etc.), it has to wait until that service replies. In mobile applications to prevent the freezing of the screen, and give the customer the impression that the process is taking actions visually, but it’s usually not. Simple processing of independent data is a great place for asynchronous programming and provides a better UX and, most of the time, better performance in your application.Ĭalvin Brown is the Founder of Kairu Consulting. It’s a quick way to have your data become out of sync. “Every situation is different and there’s no real grab-bag solution…”Īs a rule of thumb, asynchronously updating records that are dependent, or depended upon, is generally a bad idea. In the last 2 years he has created MRI Directory, Create Brief, and Headphone Charts. James is a serial web entrepreneur who builds websites with the aim of helping millions of people.
