Patterns Async + Event-Driven
Building with events sometimes requires a different way to look at the problem & solution. These common patterns walk through what the solutions look like with or without using events.
01
The Basics
Keeping your API fast
Moving code out of the critical path into background jobs to keep API response times performant
Performance
Running code on a schedule
Run task periodically, as cron jobs, like weekly emails or daily backups
Scheduling
Build reliable webhooks
Handle high throughput webhooks in a fault tolerant way
PerformanceReliability
Reliably run critical workflows
Break complex code into reliable, independently ran steps
Reliability
02
The Advantage of Events
Running functions in parallel
Fan-out work to multiple functions using a single event
Architecture
Running at specific times
Pause and wait until a specific time based off of data within an event
SchedulingArchitecture
Cancelling scheduled functions
Automatically cancel scheduled, paused, and waiting work using events
Scheduling
Reliable scheduling systems
Combine cron-jobs with event fan-out for auditable scheduling
