Performance, bulk testing, and governor-limit diagnostics

Configure or analyze a scenario involving trigger events, context variables, bulk patterns, recursion, order, and handler frameworks.
Build and validate an exercise covering service, domain, selector, utility, factory, and dependency patterns and future methods, queueable apex, batch apex, schedulable apex, and platform limits.
Use tests, logs, reports, or documentation to verify performance, bulk testing, and governor-limit diagnostics.

Explain trigger events, context variables, bulk patterns, recursion, order, and handler frameworks in the context of Salesforce Lightning Aura Components (DEX601).
Apply practical methods for service, domain, selector, utility, factory, and dependency patterns and future methods, queueable apex, batch apex, schedulable apex, and platform limits.
Test, document, and troubleshoot performance, bulk testing, and governor-limit diagnostics.
