进行分页/无限滚动时如何进行页面缓存？
我有大量数据集要显示，其中顺序不断变化（例如 SO、HN、Reddit）。由于 Rails 在页面和操作级别进行缓存，如果像本例中呈现的操作需要根据分页参数而有所不同，我该怎么办？
我能想到的几个策略：
- 仅在 redis/memcached 中进行对象缓存 - 但我的大部分时间都花在渲染上；如果我这样做，理想情况下我必须将渲染移至 javascript 并
- 使用 eTags - 但客户端仍然必须获取该页面一次。
- 缓存整个渲染的数据集，并将一些逻辑放入控制器中以获取所需的页面。使用清扫器将其过期。
我怎样才能最好地“开箱即用”？我想介绍最小的复杂性。
I have large dataset to display in which the order is constantly changing (like SO, HN, Reddit). Since Rails does caching at the page and action level, what can I do if the action rendered like in the case needs to be different depending on pagination params?
A couple strategies I could think of:
- Do just object caching in redis/memcached - but most of my time is being spent in rendering ; if I did this I'd ideally have to move the rendering into javascript as well
- use eTags - but then the client still has to get the page once.
- cache the entire rendered dataset, and put some logic into the controller to grab the page it needs. Use a sweeper to expire it.
How can I best do this "out of the box?" I want to introduce the minimum amount of complexity.
