Stored procedures gremlin CosmosDB中的存储过程

我是

gremlin

和

cosmosdb

的新手，并尝试在cosmosdb gremlin API中使用

存储过程

我从doc开始创建一个node.js应用程序，与CosmosDB gremlin API连接。现在我想在那个应用程序中使用存储过程。
我在CosmosDB中只找到了一个用于存储过程的单实例，而这只适用于DocumentDB（在SQL中）。我在gremlin中没有找到任何与存储过程相关的文档

谁能指导我，怎么做

提前感谢。
您的用例是什么

Gremlin是一种用于遍历图形的语言。Gremlin不了解CosmosDB存储过程，因此您无法通过Gremlin真正执行存储过程

然而，宇宙数据库是多模型的。您可以通过gremlin和本地documentdbapi与它对话

您应该研究如何通过DocumentDB API执行存储过程

 根据您对问题第一个答案的评论：“实际上，每次创建新顶点时，我都想添加一些边。例如，每当创建带有标签EMPLOYEE的顶点时，必须自动创建顶点公司的边。”，您可以查看TinkerPop的

如果链接发生变化，则从上面的链接添加必要的部分：

EventStrategy的目的是在遍历中对基础图进行更改时，向一个或多个MutationListener对象引发事件。这种策略对于记录更改、基于更改触发某些操作或任何在遍历过程中需要通知某些变化操作的应用程序非常有用。如果回滚事务，则重置事件队列

将向MutationListener引发以下事件：


新顶点
新优势
顶点属性已更改
边属性已更改
顶点属性已删除
删除边属性
顶点移除
去除边缘

要从遍历开始处理事件，首先实现MutationListener接口。此实现的一个示例是ConsoleStationListener，它将每个事件的输出写入控制台。以下控制台会话显示基本用法：

By default, the EventStrategy is configured with an EventQueue that raises events as they occur within execution of a Step. As such, the final line of Gremlin execution that drops all edges shows a bit of an inconsistent count, where the removed edge count is accounted for after the event is raised. The strategy can also be configured with a TransactionalEventQueue that captures the changes within a transaction and does not allow them to fire until the transaction is committed.

警告
EventStrategy不适用于跨单独流程跟踪全局突变。换句话说，一个JVM进程中的突变不会作为另一个JVM进程中的事件引发。此外，当在遍历上下文之外发生突变时，不会引发事件。

我与您有相同的问题。我发现Cosmos DB在remlin或Graph模式不支持存储过程。您可以从UI创建它们，但因为您不能使用任何Gremlin查询或触发器-它们是无用的。此外，也没有关于它的文档

我在2019年3月的一篇文章中发现，Germlin的路线图上有存储过程

就我个人而言，在我的用例中，我正在考虑使用Neo4j而不是Cosmos，因为缺少存储过程

实际上，每次创建新顶点时，我都想添加一些边。例如，每当创建带有标签
EMPLOYEE
的顶点时，必须自动创建顶点
COMPANY
的边。请执行以下操作通常，我希望在每次创建新顶点时添加一些边。例如，每当创建带有标签
EMPLOYEE
的顶点时，都会向该顶点添加一条边
