What is difference between future and Queueable Salesforce?
The main differences between @future methods and Queueable Apex jobs are: You can enqueue a queueable job inside a queueable job (no more “Future method cannot be called from a future or batch method” exceptions).
Why do we need future method?
You can use future methods for any operation you’d like to run asynchronously in its own thread. This provides the benefits of not blocking the user from performing other operations and providing higher governor and execution limits for the process. Everyone’s a winner with asynchronous processing.
Why we use future method in Salesforce?
You can call a future method for executing long-running operations, such as callouts to external Web services or any operation you’d like to run in its own thread, on its own time. You can also use future methods to isolate DML operations on different sObject types to prevent the mixed DML error.

What’s the difference between queueable jobs and future jobs?
1. Queueable Jobs can contain the member variable as SObjects or custom Apex Types. 2. When using queueable jobs it will make the AsyncApexJob which we can monitor like Scheduled jobs. 3. Queueable Apex can be called from the future and batch class.
When to use the future or queueable method?
Callouts to external Web services. If you are making callouts from a trigger or after performing a DML operation, you must use a future or queueable method. A callout in a trigger would hold the database connection open for the lifetime of the callout.
Can you get job ID in queueable apex?
It will accept non-primitive types like sObjects and it also runs in asynchronous mode. In this Queueable apex you can get Job Id to monitor the job progress.
