Apache Cassandra static column 介绍与实战 Spark大数据博客 - https://www.iteblog.com Apache Cassandra static column 介绍与实战 假设我们有这样的场景：我们想在 Cassandra 中使用一张表记录用户基本信息（比如 email、密 码等）以及用户状态更新。我们知道，用户的基本信息一般很少会变动，但是状态会经常变化， ，Cassandra 引入了 static column。同一个 partition key 中被声明为 static 的列只有一个值的，也就是只存储一份。 如果想及时了 解Spark、Hadoop或者Hbase相关的文章，欢迎关注微信公共帐号：iteblog_hadoop 定义 static column 在表中将某个列定义为 STATIC 很简单，只需要在列的最后面加上 STATIC 关键字，具体如下： "email" text STATIC, "encrypted_password" blob STATIC, "body" text, PRIMARY KEY ("username", "id") ); iteblog_users_with_status_updates 表中我们将 email 和 encrypted_password 两个字段设置为 STATIC 了，这意味着同一个 username
