We updated our GraphQL engine to be a bit smarter about how it generates the requests it sends to Salesforce. Some GraphQL queries that required multiple round trips to the Salesforce API will now generate a single, efficient SOQL query.
Staying under the Salesforce API rate limit can be a frustrating experience. OneGraph is constantly improving in the background to make it easier.
The average number of requests per GraphQL query after this change dropped from 2.3 to 1.4.
