9. What is GraphQL?
9
• GraphQL is an open-source query language for Rest API's and it is developed by Facebook
in 2012 before releasing publicly in 2015.
• RESTful APIs follow clear and well-structured resource-oriented approach. However, when
the data gets more complex, the routes get longer. Sometimes it’s not possible to fetch data
with a single request. This is where GraphQL comes handy. GraphQL structures data in the
form of a graph with its powerful query syntax for traversing, retrieving, and modifying data.
• GraphQL allows developers to retrieve data from many possible sources in a single call in
such a way that the results are predictable and are strongly typed, meaning that the caller
will know exactly what types of data will be returned.
• Examples of GraphQL- Amazon, Microsoft, PayPal, Netflix, GitHub, Airbnb and many more…

10. What is Anypoint DataGraph?
10
• Anypoint DataGraph is a component of Anypoint Platform which allows you to create
unified schema for your APIs and support dynamic query.
• It allows to discover, manage or serve the data from multiple APIs using single request.
• Anypoint DataGraph is the unified platform for APIs to design, develop & manage. It run
as SaaS app to reduce overhead and maintenance.
• It reduces a lot of efforts for developers to call multiple APIs and aggregate the response.
With Anypoint DataGraph, you can request only data you want, no more or no less.

11. Anypoint DataGraph Benefits
11
• Reduce development & maintenance efforts.
• Request the data you want, no more no less.
• Developer doesn't have to write the code to parse the data from multiple APIs.
• Anypoint DataGraph is a managed service and no need to worry about the underlying
infrastructure & maintenance.
• Unify multi-APIs in one data service. Anypoint DataGraph allows you to serve data from
multiple underlying APIs in a single query without writing code.

12. Scenario - 1
You have a Rest API that returns 10 fields in response but web app requires only 8 fields whereas mobile app requires
only 4 fields. In such cases, DataGraph is one of the most optimal options where the client can pass whatever data
required as an input request and DataGraph returns the required fields to the web & mobile app.
12
Below is the illustration of Scenario - 1

13. Scenario - 2
You have to call multiple rest endpoints or want to fetch data from multiple rest endpoints and each APIs will respond
with JSON payload. DataGraph will aggregate all the responses and send back the required data to the client.
13
Below is the illustration of Scenario - 2

14. Constraints & Limitations
14
● Anypoint DataGraph supports:
 Support mutations
 250 API's per unified schema
 16,000 fields per unified schema
 REST APIs with RAML & OAS specifications
● Anypoint DataGraph restricts downstream REST API calls to:
 A 5 second timeout per call
 Depth limiting (max of 100 depth)
 A maximum of 5 MB of response data per call
 A maximum of 150 concurrent or ongoing calls per unified schema
● Anypoint DataGraph limits the query service to:
 A 30 second timeout per query
 A maximum of 100 selected fields per query
● To enable collaboration & linking, the primary key field should be in a string type.

15. Authentication Mechanism
15
Authentication Mechanism
DataGraph support below list of Authentication mechanism while calling underlying APIs
 No Auth
 Basic Authentication
 Pass-through Authentication
 OAuth 2.0 Client Credentials
 Client Id Enforcement via Headers
 Client Id Enforcement via Query Params
 Custom (Add Custom headers or Query Params)
