Key points
- •Event patterns match against source, detail-type, and detail fields — more expressive than SNS filtering
- •One event can match multiple rules, fanning out to multiple targets based on content
- •Default bus (AWS service events), custom buses (your app), and partner buses (third-party SaaS) organize routing by domain
- •Producers don't need to know in advance which rules will match their published events
