Queueable chaining
Learn Queueable chaining in Apex with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.
Queueable chaining is an atomic Apex topic inside Asynchronous Apex. The example below uses the actual construct named by the lesson rather than a generic placeholder.
Focus on what Queueable chaining changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.
Topic-specific example
public class FirstJob implements Queueable { public void execute(QueueableContext c){ System.enqueueJob(new SecondJob()); } }
Observe when work actually runs, what state crosses the asynchronous boundary, and how completion or failure is surfaced.
