What is asynchronous process in Salesforce?
An asynchronous process is a process or function that executes a task “in the background” without the user having to wait for the task to finish.
What is difference between synchronous and Asynchronous in Salesforce?
In Synchronous process the thread waits for the task to be completed and then moves to the next task Sequentially. All the tasks are completed in a single thread. In Asynchronous apex the thread does not waits for the task to be completed to move on to the next task. The tasks are run in different threads all together.
What is the difference between synchronous and Asynchronous?
What is the difference between synchronous and asynchronous instruction? Synchronous learning is interactive, two-way online or distance education that happens in real time with a teacher, whereas asynchronous learning occurs virtually online and through prepared resources, without real-time teacher-led interaction.
How are asynchronous processes executed in Salesforce?
Asynchronous processes are queued in salesforce and are executed as soon as resources are available. But there is no guarantee when this will be executed. Hence not suitable for processes if some time sensitive action is planned based on the outcome of this process Asynchronous processing includes @future Apex, batch Apex or scheduled apex.
Is there a way to run Apex code asynchronously?
Apex offers multiple ways for running your Apex code asynchronously. Choose the asynchronous Apex feature that best suits your needs. This table lists the asynchronous Apex features and when to use each.
When to use queueable apex in Salesforce force?
Queueable Apex: When one task is dependent on completion of another task we make use of this asynchronous feature, Also job chaining and complex type of jobs are achieved using this feature Image Source: https://developer.salesforce.com/page/Asynchronous_Processing_in_Force_com
How to write asynchronous apex-sfdevops unit test?
Create an Apex class that uses Scheduled Apex to update Lead records. Create an Apex class that implements the Schedulable interface to update Lead records with a specific LeadSource. Write unit tests that achieve 100% code coverage for the class. This is very similar to what you did for Batch Apex.
