Multiple query execution combines multiple queries into a single query, executing them in the same requested order, while allowing them to communicate state with each other via dynamic variables.
query GetLoggedInUserName {
me {
name @export(as: "loggedInUserName")
}
}
query FindPosts @depends(on: "GetLoggedInUserName") {
posts(filter: { search: $loggedInUserName }) {
id
title
}
}This feature offers several benefits:
- Performance: Instead of executing a query against the GraphQL server, then wait for its response, and then use that result to execute another query, combine the queries together into one and execute them in a single request, thus avoiding the latency from the multiple HTTP connections.
- Functionality: Adapt field values as needed. Query some value from the database in one operation, and transform it and inject it into another field on another operation.
- Modularity: Manage your GraphQL queries into atomic operations (or logical units) that depend on each other, and that can be conditionally executed based on the result from a previous operation.
