是的，Hugegraph确实支持动态数据更新的场景。这可以从提供的上下文中的`HugeElementFeatures`类看出，该类有`supportsAddProperty()`和`supportsRemoveProperty()`方法，这两个方法都返回`true`。这些方法表明可以向元素（顶点和边）添加和删除属性，从而允许对图数据进行动态更新。

`GraphTransaction`：这用于对图数据本身的操作。例如，添加或删除顶点和边，查询顶点和边等。这些操作必须手动提交，如`graphTransaction()`方法中的注释所示。

`SchemaTransaction`：这用于对图的模式的操作。每个模式操作将自动提交，如`schemaTransaction()`方法中的注释所示。

当执行数据更新操作时，使用适当的方法（`openGraphTransaction()`、`openSystemTransaction()`或`openSchemaTransaction()`）打开新的事务。然后在此事务中执行操作。如果操作成功，事务被提交，更改被永久保存。如果操作过程中出现错误，事务被回滚，更改被丢弃。
