Schema Modularization with Type Extensions
Keep large GraphQL schemas maintainable by splitting them into multiple SDL files and extending shared root types with the extend keyword in Spring Boot.
The Monolithic Schema Problem
As an API grows, a single schema.graphqls file becomes thousands of lines, hard to navigate and prone to merge conflicts.
Modularization splits the schema by feature so each team owns a focused slice.
Modularization vs Stitching
This is different from schema stitching. Stitching merges schemas from separate services. Modularization splits one service's schema into many files that load into the same runtime.
