Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Bulk Triggers

All triggers are bulk triggers by default, and can process multiple records at a time. You should always plan on processing more than one record at a time.

An Event object that is defined as recurring is not processed in bulk for insert, delete, or update triggers.

Note

Bulk triggers can handle both single record updates and bulk operations like:
  • Data import
  • Lightning Platform Bulk API calls
  • Mass actions, such as record owner changes and deletes
  • Recursive Apex methods and triggers that invoke bulk DML statements
