Object Pool Pattern
Explore how the object pool pattern allows pre-creating and managing a pool of reusable resources, such as database connections, to improve performance and concurrency in backend services. Understand scenarios where this pattern is beneficial and how to implement it safely in Go for scalable applications.
We'll cover the following...
Description
The object pool design pattern is a creational design pattern in which a pool of objects is initialized and created beforehand and kept in a pool. As and when needed, a client can request an object from the pool, use it, and return it to the pool. The object in the pool is never destroyed.
When to use
We want to use the object pool pattern in the following scenarios:
Avoid high runtime creation cost: Use when the cost to create an instance of a class on the fly is high and the number of such instances that will be needed at a particular time is limited.
Let’s take ...
