Mastering Apex Trigger Frameworks and Bulkification Patterns

Scalable Trigger Architecture for Enterprise Salesforce Orgs

A well-architected Apex trigger framework ensures 100% bulkification, prevents trigger recursion, enforces single-responsibility handlers, and bypasses governor limit bottlenecks.

// Production Apex Trigger Handler Pattern
public with sharing class AccountTriggerHandler implements ITriggerHandler {
    private static Set<Id> processedIds = new Set<Id>();

    public void beforeInsert(List<Account> newRecords) {
        // Enforce OWD & Record Data Cleanliness
        AccountService.standardizeTaxIds(newRecords);
    }

    public void afterUpdate(List<Account> newRecords, Map<Id, Account> oldMap) {
        List<Account> recordsToProcess = new List<Account>();
        for (Account acc : newRecords) {
            // Prevent Recursion using static set verification
            if (!processedIds.contains(acc.Id) && acc.AnnualRevenue != oldMap.get(acc.Id).AnnualRevenue) {
                processedIds.add(acc.Id);
                recordsToProcess.add(acc);
            }
        }
        if (!recordsToProcess.isEmpty()) {
            System.enqueueJob(new SyncRevenueQueueable(recordsToProcess));
        }
    }
}
