Limit query cost
Define a maximum cost applied to any query, regardless of whether or not the call is within the rate limits for a consumer.
By defining a max_cost on the upstream service, you ensure that no query will run with a cost higher than the set max_cost.
By default it’s set to 0, which means no limit.
Prerequisites
- You have an existing a GraphQL upstream service.
