Bulkification

In plain words: Governor Limits are Salesforce's traffic rules for multi-tenant architecture. Because many companies share the same underlying cloud infrastructure, Salesforce enforces strict transaction caps (like memory, queries, and CPU time) so one piece of inefficient code cannot slow down or crash the shared platform. Salesforce executes Apex code in a multi-tenant cloud environment. To guarantee high performance, platform stability, and fair resource sharing, the runtime engine enforces strict per-transaction limits known as Governor Limits . When code exceeds these boundaries, Salesforce throws a fatal runtime LimitException that immediately halts execution. Writing resilient Apex requires a clear understanding of these boundaries and defensive design patterns. 1. Understanding Core Governor Limits Governor limits monitor resources across synchronous and asynchronous transactions. Understanding these thresholds is essential for designing high-thro...

In plain words: An Apex Trigger Cheatsheet is a quick-reference guide that summarizes the essential syntax, context variables, and lifecycle events required to automate business logic when records are created, updated, or deleted in Salesforce. It provides clean code snippets and best practices to help developers write fast, bulkified, and scalable backend automation. Apex triggers are powerful server-side blocks of code that execute before or after database events occur on Salesforce objects. Understanding trigger execution events, context variables ( Trigger.new , Trigger.oldMap ), and architectural standards like the "One Trigger Per Object" rule ensures your code runs efficiently and stays well within platform governor limits. 1. Trigger Syntax and Structure An Apex trigger is defined on a specific sObject and listens for one or more database event keywords: trigger AccountTrigger on Account (before insert, before update, after insert, after u...
