The travel industry is shifting towards delivering personalized experiences to customers by consolidating data from multiple sources into a unified view. To achieve this, companies are leveraging Apollo GraphOS and Apollo Federation, which offer a solution that combines the benefits of a federated model with the flexibility required for service decomposition. This enables travel companies to maintain a single unified view of their data while still leveraging the advantages of microservice architectures. GraphQL federation allows services to manage dependencies between services, ensuring a complete and accurate customer view. By using federation-specific directives like `@key`, services can mark up their schemas to indicate the fields they depend on or provide to other services, which enables the graph to intelligently track and resolve these dependencies. This results in simplified client logic required to fetch and display user data, such as trip suggestions, with a single request.
