Hot Swapping
Hot swapping is a software development technique that allows code changes to be applied to a running application without restarting it, enabling continuous updates and reducing downtime. It is commonly used in development environments, server applications, and embedded systems to facilitate rapid iteration and debugging. This capability supports dynamic reloading of modules, classes, or configurations while maintaining application state.
Developers should learn hot swapping to improve productivity in development workflows, as it allows for immediate testing of code changes without the overhead of restarting applications, which is especially useful in long-running processes like web servers or game engines. It is critical in scenarios requiring high availability, such as live production systems where minimizing downtime is essential, and in iterative development cycles for faster feedback loops.
