推荐答案

Cassandra的两个核心概念是表被设计为服务于一个查询，并且不支持这些选择.当然，您可以在应用程序级别执行此操作.

Two of Cassandra's core concepts is that the tables are designed to serve one query and it does not support these kinds of selects. Of course, you could do that at your application level.

因此，答案是否定的，它将不支持此类查询.

So, the answer in no, it won't support such query.
