Optimizing Apex Triggers for Bulk Operations: Best Practices for Performance

Scalable Apex Development

In high-volume Salesforce environments, poorly written Apex triggers can quickly become a bottleneck. Mastering bulkification is essential for any serious Salesforce developer.

One Trigger Per Object

The golden rule of trigger design is to have only one trigger per object. This ensures predictable execution order and makes debugging significantly easier.

trigger AccountTrigger on Account (before insert, before update) {
    if (Trigger.isBefore) {
        if (Trigger.isInsert) {
            AccountService.handleBeforeInsert(Trigger.new);
        }
    }
}

Efficient Querying

Always query outside of loops. Use Maps to store queried data for efficient lookups during processing.

• Avoid SOQL in loops
• Handle null checks gracefully
• Use Trigger Frameworks for scalability
