传统RDBMS的最大价值在于，它可以将单独的表联接在一起，从而创建其中所包含数据的不同视图。

The greatest value of a traditional RDBMS comes from its ability to join individual tables together to create different views of the data contained therein.

如果您想故意实现这种行为，或只发生了一个单独的后续执行，又或者并行的分支在到达某个单独的停止节点之前已经重新联接，那么您可以安全地使用这些停止节点。

You can safely use them when this behavior is intended, when only a single sequential execution occurs, or when parallel branches rejoin before reaching a single stop node.
