Architectural Decision Matrix: Low-Code Automation vs Pro-Code Apex
With record-triggered Flow performance improvements in recent releases, architects must evaluate maintainability, transaction limits, and execution speed before deciding between Flow Builder and Apex Triggers.
Comparison Matrix
• Before-Save Validation & Field Updates: Use Fast Field Update Record-Triggered Flows (executed before database commit, 10x faster than process builder).
• Complex Business Logic & Map Manipulations: Use Apex Triggers for heavy list sorting, complex math, or multi-object DML loops.
• Invocable Apex Actions: Combine low-code Flow orchestration with invocable Apex methods for API integrations.
