What Is Object Pooling?

In software development, there's much talk about "pools." what exactly is Object pooling? Why should you care? Object pooling is a service that lets you keep all your components in a pool, ready to be used by any requesting client. It's like having a ton of spare tires just sitting around in case you break down, but instead, they're made out of code, and they're all made perfectly to fit your car. The best part? You don't have to worry about checking whether the tires are still good. The object pool will do that for you! In real life, it could be used for anything from renting an apartment or house to sharing a car or ride-sharing service with friends. In computer science, it's just sharing instances of components with other people who need them, and it's used in all kinds of applications today. Object pooling is a way to save money. It's not just that the object pooling saves you time. It also saves you money. Unlike other intelligent, efficient ways of doing things, like using singleton or thread pools, object pooling is so thoughtful and efficient that it can save you money! It works when your application starts up. It needs to construct and initialize all these expensive objects. What if you could do that in advance? What if there was a way to allocate all those resources ahead of time? That way, when you start your application and are ready to do some work, all those resources are already waiting for you! This is where object pooling comes in. With object pooling, instead of creating and destroying objects every time they're needed (which costs money), we can make them once before starting our program and keep them around until we need them again. This means we don't have to pay for those expensive initializations repeatedly!
