Scaling Rails with Cache-on-write
原标题:

I currently have a rails app that uses the traditional caching. cache do blocks are used to cache slow-rendering partials. This works great for the most part, except for a few pages which take too long to render on the first read.

I d like to move the rendering of these partials to the write-side from the read-side, by rendering in either the model or in sweepers when the underlying data changes. Preferably, this would be in the sweepers that already invalidate the cache keys. Is this a good approach? Is there a "right" way to do this?

问题回答

Is it the actual partial that is taking a while to render or the queries required to actually get the data? If it s the latter you re better off caching those in a write-through manner, it might be simpler than trying to update cached partials on write.
