记录的统计数据,该使用数据库冗余字段还是即时查询,或者其他方式?

如题。统计字段通常显示和更新都很频繁,该如何高效的处理这类型的数据呢?
比如SF的问题回答数、收藏量、投票数等统计数据。请给个好的解决方案,谢谢!

我是这样处理的.我先垂直分表.然后按需延时写入.

对于这类读写频繁的数据:
1.如果请求量并不算特别高可以考虑另外维护一份InnoDB引擎的表,单独存统计数据,实时查询更新基本能满足;
2.如果请求量非常高则考虑存储在内存型数据库中(譬如Memcache、Redis),如果数据需要落地(永久保存,内存型数据库或多或少都有数据丢失的风险)就另外加个计划任务定时将数据写入数据库中,万一内存里面的数据丢失可以重新从数据库读取。
