这主要是 DSE/Search 的性能问题，因为查询需要在内部扇出到足够多的节点(或 vnodes)以覆盖所有 Cassandra 行在 DC 中，启用 vnode 时会出现更多子查询.

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/搜索 DC 中使用虚拟节点的性能可以接受，那么您就无需担心.

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