Understanding the query cost calculation
In DoS attacks, we have many different possibilities of feeding the server with too much data, and we can protect ourselves from all of them by using the query cost calculation method. This requires additional middleware and extra work from us, but it should be worth implementing on bigger APIs.
Query cost calculation in GraphQL involves assigning a numerical value to each field in the schema to determine the overall cost of executing a given query. This allows for resource management and optimization, ensuring that queries do not consume excessive server resources.
Let’s explore another example schema to understand how query cost calculation works. In this schema, we will have Product, which can have Reviews, and each Reviews has a corresponding Author. Here, we’ll assign a cost value to each field based on its complexity and the resources it requires. For simplicity, we’ll use a scale from 1 to 10, where 1 represents...
