Your logic is slightly flawed. All async code can run in to stale data. Overview. The main differences between @future methods and Queueable Apex jobs are: When you enqueue a new job, you get a job ID that you can actually monitor, like batch jobs or scheduled jobs! You can enqueue a queueable job inside a queueable job (no more “Future method cannot be called from a future or batch method” exceptions).

Why should we use Queueable apex when we can perform chaining of batches in batch apex (when we can call another batch in the finish method) 0. 2 Answers. For now, the delay implementation will be baked into the processing class itself. apxc public class CustomerInteractionHandler implements Queueable {private List < Customer_Interaction__b > interactions;. Using asynchronous automations is increasingly important as the business processes and. Why I want to do that: To increase debugging speed. Using the interface is an enhanced way of running your asynchronous Apex code compared to using future methods. batch. You can implement a Queueable class that acts as a Future method and then you can invoke another future method. getEventBus (). Using Queueable Apex will chain up to queueable jobs and in Developer Edition it is only 5 Jobs. Using Batch Apex, you can process records asynchronously in batches (hence the name, “Batch Apex”) to stay within platform limits. Among these are complex asynchronous automations including Queueable, Batch, and Schedulable Apex. So my question as I am enqueuing only one class.
