关于无主复制的疑问 about ddia HOT 3 CLOSED

我理解是对 row 或 document 更新时，不直接更新当前的记录，而是创建一条新的记录，最终通过时间戳等来区分先后，避免并发更新同一条记录可能带来的不安全。

这是原文，
The only safe way of using a database with LWW is to ensure that a key is only written once and thereafter treated as immutable, thus avoiding any concurrent updates to the same key. For example, a recommended way of using Cassandra is to use a UUID as the key, thus giving each write operation a unique key.

原文中对最后一句话还有一个引用，文章的标题是：
Jonathan Ellis: “Why Cassandra Doesn’t Need Vector Clocks,” datastax.com, September 2, 2013.

没有进一步的疑问我就先关闭这个 Issue 了哈。
