这主要是DSE / Search的性能问题，因为查询需要在内部散布到足够多的节点（或vnode）以覆盖DC中的Cassandra行的全部范围，启用vnode时会有更多子查询。

It is primarily a performance concern with DSE/Search since a query needs to fan out internally to enough nodes (or vnodes) to cover the full range of Cassandra rows in the DC, that's a lot more sub-queries when vnodes are enabled.

但是，如果您在DSE / Search DC中使用vnode的性能可以接受，那么您就不必担心。

But, if your performance with vnodes in a DSE/Search DC is acceptable, then you have nothing to worry about.
