_🤖_ <!-- Greeting --> 你好 @imbajin，我是[Dosu](https://dosu.dev)，一个可以帮助你解决问题和成为贡献者的机器人。在等待人类维护者的回复期间，我会尽力为你提供帮助。很高兴能够和你相识！ <!-- Answer --> 您的理解基本正确，但是具体的实现细节可能会因为不同的查询类型和配置而有所不同。在HugeGraph中，一次完整的API读取（如Kneighbor）的过程大致如下： 1. 当向"/graphs/{graph}/traversers/kneighbor"端点发出GET请求时，会调用`get`方法。此方法接收源顶点、方向、边标签、深度、最大度和限制等参数。然后，它创建一个`KneighborTraverser`实例，并调用其`kneighbor`方法来获取源顶点的K邻居。如果`countOnly`参数为true，它将返回K邻居的数量；否则，它将返回K邻居的ID。 2. 当向同一端点发出POST请求时，会调用`post`方法。此方法接收一个`Request`对象，该对象包含源顶点、步骤、最大深度、限制以及是否返回顶点、路径和边的标志等参数。然后，它创建一个`KneighborTraverser`实例，并调用其`customizedKneighbor`方法来根据指定的步骤获取源顶点的K邻居。根据`Request`对象中的标志，它还可能返回与K邻居相关的顶点、路径和边。 至于HugeGraph-server是否支持多用户同时查询，多业务同时查询的问题，HugeGraph-server是设计为能够处理多个并发请求的。然而，实际的并发级别取决于服务器的配置和底层系统的资源。提供的代码没有显示任何明确的同步或锁定机制，这表明服务器依赖于底层数据库和系统资源来处理并发请求。 相关源码： - [hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/api/traversers/KneighborAPI.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/api/traversers/KneighborAPI.java) 如果您有更多的问题或需要进一步的解释，请随时提问。 ## Sources - [hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/api/traversers/KneighborAPI.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/api/traversers/KneighborAPI.java) - [hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/traversal/algorithm/KneighborTraverser.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/traversal/algorithm/KneighborTraverser.java) --- This response is meant to be useful and save you time.
