In a unified setup, you often rely heavily on Pipeline Resolvers . These allow you to chain functions (e.g., Auth Check -> Get Data -> Transform Data). While powerful, debugging a chain of 4-5 Lambda functions triggered by one field resolver is difficult. CloudWatch logs can get fragmented, making it hard to trace a single request end-to-end.
This gives maximum flexibility but requires maintaining the composition logic. appsync unified repo
To manage the complexity that arises when multiple teams contribute to a merged API, adopting principles is highly recommended. Structuring your source APIs around business capabilities rather than technical concerns creates clearer boundaries, reduces conflicts, and improves maintainability. In a unified setup, you often rely heavily
A unified AppSync repo simplifies coordinated development across schema, resolvers, and functions while enabling stronger typing, testing, and CI/CD. Start small, modularize by domain, automate validation and ephemeral environment testing, and use IaC to keep deployments reproducible and safe. CloudWatch logs can get fragmented, making it hard
