This episode introduces asynchronous processing in Salesforce, contrasting it with synchronous operations by highlighting its ability to execute tasks "in the background" without user waiting. It emphasizes key benefits like user efficiency, allowing immediate continuation of work, and scalability, which enables the platform to manage and process more jobs concurrently. A significant advantage detailed is the provision of higher governor and execution limits for asynchronous processes, effectively doubling capacities for operations like SOQL queries. This episode further outlines different types of asynchronous Apex - Future Methods, Batch Apex, Queueable Apex, and Scheduled Apex - explaining their unique applications, and concludes by describing the queue-based framework that manages and ensures the fair, fault-tolerant processing of these requests in a multi-tenant environment.

A hard delete is a specific API-based operation that permanently deletes records from Salesforce, completely bypassing the Recycle Bin. Once a record is hard deleted, it is gone forever and cannot be recovered by any user, including administrators.

Yes, there is a special permission in Salesforce designed specifically for this purpose. It is a powerful administrative permission called "Edit Read Only Fields."

This permission allows a user to edit fields that are normally not editable due to security or page layout settings. However, it is crucial to understand both what it can override and what its limitations are.
