I am happy that Cassandra 3.0 is out now and thought i'd check the documentation. This documentation page states that 3.0 offers support for materialized views.
Is this feature still in progress (why then stated in the "new features" section?) or how is it used?
有一些“何时使用，何时不使用”的要点进行了很好的演练： http ://www.datastax.com/dev/blog/new-in-cassandra-3-0-materialized-views https:// docs.datastax.com/en/cql/3.3/cql/cql_reference/refCreateMV.html
1.2 太旧了。最新的 CQL 文档适用于 2.2 http://cassandra.apache.org/doc/cql3但这仍然太旧，似乎还没有添加 3.0 版本（3.0 还很新）。
