Using Queueable Apex; Using the Finish method of Batch class. Apex however lacks something like the unix "at" command - the ability to queue up one-off jobs to run at a specified time. It allows you to submit jobs for asynchronous processing with some additional benefits comparing to @future methods. The execution of a queued job counts once against the shared limit for asynchronous Apex method executions. Sorted by: 8. This feature has a lot of potential, especially if it can be expanded beyond just the Queueable context. Queuable Apex - chaining jobs vs calling other classes synchronously. Queueable Jobs can contain the member variable as SObjects or custom Apex Types. 2. After each request comes back with a successful response, the next class will fire and make another request to a. So atmost 100 jobs can be added in one go. 1100. It uses the Queueable interface which is an enhanced way of running. batch. This interface enables you to add jobs to the queue and monitor them. Right now, in my org's account trigger handler class, we do various separate complex queries/calculations/DML operations. 非同期 Apex プロセスを制御するには、Queueable インターフェースを使用します。このインターフェースにより、ジョブをキューに追加して監視できます。このインターフェースを使用することで、future メソッドを使用する場合に比べ、非同期 Apex コードの実行が機能強化されます。Queueable Apex has the ability to (1) start a long-running operation and get an ID for it, (2) pass complex data types like sObjects to a job, and (3) chain jobs in a sequence. In order to prevent a crash from killing your transaction entirely, I would suggest a Batchable class (or you could Queueable with Finalizer, but that may be overkill).

Have your Queuable set Run_Queueable__c to false when it has nothing left to process, otherwise keep re-queueing itself until everything is done; Have a trigger on the queue items which does an upsert with the queueable name and Run_Queueable__c = true; This ensures that only one Queuable is running at once. Previously, a queueable job could make a web service callout, but additional chained jobs that made callouts would throw exceptions. To execute Apex as an asynchronous job, implement the Queueable interface and add the processing logic in your implementation of the execute method.
