Description

This course opens on the night a rating run did not finish, and everything after it is about why. It is the Apex course for code that has to survive volume: what a transaction actually costs, trigger design at scale, transactional integrity when things fail halfway, asynchronous Apex done properly, selective SOQL against large data volumes, dynamic Apex, platform events, and integration in both directions.

It assumes you can already write Apex. What it adds is the judgement to look at a working class and see where it will fall over in eighteen months, and the techniques to measure that rather than guess.

Who this course is for

  • Working Salesforce developers whose code now runs against real volume.
