What Is Batch Class In Salesforce

How to prepare for Salesforce developer interview

Batch class in salesforce is used to run large jobs that would exceed normal processing limits. Using Batch Apex, you can process records asynchronously in batches to stay within platform limits. If you have a lot of records to process, for example, data cleansing or archiving, Batch Apex is probably your best solution.

Heres how Batch Apex works under the hood. Lets say you want to process 1 million records using Batch Apex. The execution logic of the batch class is called once for each batch of records you are processing. Each time you invoke a batch class, the job is placed on the Apex job queue and is executed as a discrete transaction.
