Modern flight booking systems must integrate with multiple airline providers to offer search results. Each provider responds at a different speed and may fail independently.
The challenge is building a system that can dispatch requests to all providers simultaneously, collect responses as they arrive, and present progressive results to users in real-time.
📄This guide shows how to solve that aggregation problem.
🧩The code is available on GitHub.
See results as early as possible.
Users need immediate feedback. Progressive results add value. Waiting for all sources is unacceptable.
Clicking the Search Flights button triggers the search operation. Immediate response is received with: search ID.
Users see results as soon as the first provider responds. Slow or failing providers never block feedback.
Monitor the status of each provider through log entries output.
Responsiveness over simplicity.
A combination of system design patterns within the hexagonal architecture boundary.
All elements coordinate under the strict discipline of a proven architectural pattern.
A message routing pattern that involves broadcasting requests to multiple recipients, and aggregating their responses back into a single message.
