Lesson: 39 | What is interface in Batch Apex?

Notes

Notes

In Batch Apex, an interface is a blueprint or a contract that defines the methods that a batch class must implement. The interface provides a standard set of methods that allow Salesforce to manage batch jobs more efficiently.

The "Database.Batchable" interface is used in Batch Apex to define a batch class, and it contains three methods that must be implemented by the batch class:

Start method: This method identifies the scope of the batch job and returns an iterable of the records that need to be processed.
Execute method: This method processes the records in the batch. It takes a list of records and processes them in bulk.
Finish method: This method runs after all batches have been processed. It performs any necessary cleanup or post-processing tasks.

By implementing these methods in a batch class, you can process large sets of data asynchronously and avoid exceeding platform limits.
