Description: Schema stitching is a technique for combining multiple GraphQL schemas into a single one. This practice allows developers to integrate different data sources and services into a single API, facilitating the management and access to information. Schema stitching is based on the idea that each schema can define its own types, queries, and mutations, and by merging them, a global schema is created that can be queried consistently. This technique is particularly useful in microservices architectures, where different services may have their own GraphQL schemas. By stitching these schemas together, greater flexibility and scalability are achieved, allowing developers to work more efficiently and keeping applications organized. Additionally, schema stitching promotes code reuse and modularity, as each schema can be developed and maintained independently before being integrated into the global schema. In summary, schema stitching is a powerful tool in the GraphQL ecosystem that enhances the interoperability and cohesion of APIs, enabling developers to build more robust and adaptable applications.
