What is the exact logic behind Queueable apex accomodating sObjects and Future method not accomodating it?.Can someone please explain it . TIA
Queueable Apex is a type of Apex class that allows you to add jobs to the Apex job queue. These jobs are processed asynchronously, meaning they are not executed immediately, but rather at a later time when system resources become available.
One key feature of Queueable Apex is that it allows you to specify the sObjects (Salesforce objects) that are passed as arguments to the class's constructor or execute method. This means that you can pass sObject records to a Queueable Apex job and then reference those records within the job's code.
On the other hand, Apex methods marked with the @future annotation are executed asynchronously, but they do not allow you to pass sObjects as arguments. This is because @future methods are intended to be used for simple, independent tasks that do not require access to specific sObject records.
The reason for this difference in behavior is that sObjects can only be passed within the same transaction as the Apex code that references them. Because @future methods are executed asynchronously, they are not part of the same transaction as the code that calls them, so sObjects cannot be passed as arguments.
In contrast, Queueable Apex jobs are added to the Apex job queue and are executed at a later time, but they are still part of the same transaction as the code that adds them to the queue. This allows them to access sObjects passed as arguments.
