When you’re scheduling tasks in CodeIgniter 4, it’s not uncommon to run into issues where the same task gets triggered before the previous one finishes. This can cause anything from duplicate processing to race conditions and even server slowdowns.

These jobs can include sending emails, processing data, generating reports, and more. Using a queue system helps offload time-consuming or resource-intensive tasks from the main application, ensuring that the application remains responsive.
