FriendFeed如何使用MySQL存储无Schema数据

How FriendFeed Uses MySQL to Store Schema-less Data

如何不断增加新功能,不断更新底层的数据库结构和数据库中存储的数百万条已有记录,还要同时支持新旧功能。FriendFeed给出他们对这些问题的答案。

Bret Taylor of FriendFeed describes a'schemaless solution'to the problem of'storing data with flexible schemas and building new indexes on the fly,'for a rapid growth website.The problem itself comes from the need to constantly add new features and update the underlying database structure,and the millions of existing records stored in that database,to support both the old and new features.FriendFeed's solution was to build'a schemaless solution on top of MySQL instead of moving to a different technology base.
