I agree Queueable apex does seem to be salesforce answer to the above type of scenario but this is our first attempt at doing something like this and we were not aware of this until now. The following code sample shows how to test the execution of a queueable job in a test method. . Create a Queueable Apex class that inserts the same Contact for each Account for a specific state. Step 5 – This is the syntax. Fixing the DataProcessor. After struggling with this for longer than I'd like to admit, I found a method that enables us to test Platform Event Triggers that enqueue Queueable jobs.

Queueable Jobs can contain the member variable as SObjects or custom Apex Types. Flows typically take longer to edit than code, do not run efficiently, and may cause problems on bulk updates. The main difference between the two techniques is that with future methods, you can't make any future calls, but with Queueable, you're allowed one more Queueable call. Using Batch Apex, you can process records asynchronously in batches (hence the name, “Batch Apex”) to stay within platform limits. try and make each queueable do as much batched work as possible to avoid chaining; UPDATE V57.

One such limit is applied to the maximum number of Asynchronous Apex method executions (batch Apex, future methods, Queueable Apex, and scheduled Apex) per a 24-hour period. Once you surpass a chain depth of 4, Salesforce will slow you down to 15 seconds between executions. AllowsCallouts to. 0. 4. The maximum batch size in a platform event trigger is 2,000 event messages. An Apex trigger processes platform event notifications sequentially in the order they’re received. Variables are stored in the heap, so if you take the data from the first queueable job, make it available to the second queueable job, and have the second queueable job query additional data on top of that, it'll naturally take more heap space than the first queueable job did.
