AWS Neptune:查询超时值

4

我运行了一条长查询(可能要两分钟),但代码崩溃并显示超时错误。

我没有使用Gremlin服务器,我直接从Python代码连接到Neptune端点。

对于NEO4J,我更改了位于https://github.com/apache/tinkerpop/blob/master/gremlin-server/conf/gremlin-server-neo4j.yaml的。

当我不使用Gremlin服务器时,如何更改类似于Neptune的设置?

超时时间设置为20秒,但仍然出现问题。这是否不寻常?超时时间应该更长吗?此操作是向图形数据库添加50个顶点。 - Uche Ozoemena
