Asynchronous Apex

Apex ProgrammingAsynchronous ApexMove work out of the user's transaction with @future, Queueable (chaining, Finalizers, AsyncOptions), Batch Apex, Schedulable and Apex cursors — and learn to monitor, limit, test and design async jobs that are idempotent and retry-safe.Intermediate · about 85 minutesWhat you will learn

Explain why and when to run Apex asynchronously and choose the right async tool

Write Queueable jobs with chaining, Finalizers, delays, stack-depth limits and duplicate signatures

Build Batch Apex with QueryLocator or Iterable, Database.Stateful and BatchApexErrorEvent error handling

Schedule jobs with cron expressions and monitor them with AsyncApexJob and CronTrigger

Use Apex cursors to process large result sets in chunks across Queueable jobs

Design idempotent, retryable async processes and test them with Test.startTest/stopTest
