全局配置

通过模式配置，可以全局禁用特定类型的操作。要单独设置操作，请参阅类型配置.

例如，如果要一次性禁用所有顶级聚合操作，Neo4j GraphQL 库通过使用@query的模式扩展提供此选项

type Movie {
    title: String
    actors: [Actor!]! @relationship(type: "ACTED_IN", direction: IN)
}

type Actor {
    name: String
    movies: [Movie!]! @relationship(type: "ACTED_IN", direction: OUT)
}
extend schema @query(read: true, aggregate: false)

查询

电影
moviesAggregate
moviesConnection
演员
actorsAggregate
actorsConnection

无效的模式使用

相同的模式配置指令不能同时应用于模式和对象。以以下类型定义为例

type Movie {
    title: String
    actors: [Actor!]! @relationship(type: "ACTED_IN", direction: IN)
}

type Actor @query(read: false, aggregate: true) {
    name: String
    movies: [Movie!]! @relationship(type: "ACTED_IN", direction: OUT)
}
extend schema @query(read: true, aggregate: false)

此配置会导致错误"@query directive already defined at the schema location"。
