What Is Batch Class In Salesforce

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.

What Are Governor Limits In Salesforce

In Salesforce, it is the Governor Limits which controls how much data or how many records you can store in the shared databases. Why? Because Salesforce is based on the concept of multi-tenant architecture. In simpler words, Salesforce uses a single database to store the data of multiple clients/ customers. The below image will help you relate to this concept.

To make sure no single client monopolizes the shared resources, Salesforce introduced the concept of Governor Limits which is strictly enforced by the Apex run-time engine.

Governor Limits are a Salesforce developers biggest challenge. That is because if the Apex code ever exceeds the limit, the expected governor issues a run-time exception that cannot be handled. Hence as a Salesforce developer, you have to be very careful while developing your application.

Different Governor Limits in Salesforce are:

• Per-Transaction Apex Limits
• Push Notification Limits
