The unified schema is a single, always-current collection of types from different API schemas that has been added to Anypoint DataGraph and made available for consumers to query. This helps us query across the underlying APIs without needing to understand all of the relationships or specific capabilities that exist within each of them. Whenever a new API is added to the application network, Anypoint Platform stores it as a graph of metadata and in turn connects those graphs into one unified schema that runs as a single SaaS GraphQL endpoint and contains and links all of the fields defined within all of the APIs. Discover, reuse and serve information from the application network without writing new code.Explore the application network from a single UI.Dynamically query data from a unified schema.This can improve the productivity and reduce operational costs by discovering and reusing the existing data in the application network. It allows us to dynamically query the unified schema and consume the field that is needed to create new connected experiences. As a result, we can query across the underlying APIs without needing to understand all the relationships or specific capabilities that exist within them. It contains all the links and fields defined in the APIs. Anypoint DataGraphĪnypoint DataGraph enables us to connect with the above graphs into one unified schema that runs as a single SaaS (Software as a Service) GraphQL endpoint. Anypoint DataGraph Framework (licensed, only for Mule 4).The above use case can be achieved using two options:
#Peak fit in datagraph code
Here, according to the REST API architecture we need to create two endpoints, but with GraphQL we can achieve the above scenario with a single endpoint without any code change. As per the requirement, the web application expects only 6 fields in response, whereas the mobile application expects only 4 fields. There is a REST API that returns 8 fields in response, for both mobile application and Web Application. MuleSoft can function as the integration layer between the end systems and the GraphQL API that is exposed. However, accessing data from different data sources requires robust connectivity and performance that is highly scalable. Integration - GraphQL provides an easy-to-use interface to query data from different data sources in a single API call.GraphQL makes it simple to query data using web standards wherein SQL expertise is not needed to access the data. Easy Access to Relational Data - The traditional way of obtaining relational data from a data source involves writing SQL queries and joining data across different tables which makes it difficult with nested data with parent-child relationships.GraphQL returns only the data that is explicitly requested enabling new capabilities to be added easily. Simple Versioning - Traditional APIs have challenges with versioning and backward compatibility and for that the version needs to be passed in the endpoint or in headers.This fastens the application performance and is a key factor for slow internet devices. Over-fetching of data is prevented - GraphQL lets us pre-define what JSON format is the data needed and this helps us get the data returned what is exactly needed with my request.By this way, front end developers are benefitted as they can easily get data and build their APIs faster. GraphQL enables a single endpoint for querying data across multiple endpoints. Multiple Endpoint Usage Is enabled - There may be multiple APIs to which a single request may span.This way we need to create less APIs to meet the different needs, adding to the reusability aspect of the APIs. It aggregates the request data and returns only relevant results. GraphQL also helps reduce the time it takes for the transaction to take place. In doing so, it cuts down on the amount of data they receive while executing a query, allowing users to focus on exactly what they need. GraphQL is an open-source query language built by Facebook in 2012, that allows users to choose the fields they are interested in.
