Subject Re: Question: Application of QueryCompilationCache for find() and lazy relationships?
Date Thu, 11 Oct 2007 17:01:02 GMT
The query compilation cache doesn't cache data that would be directly
useful for those calls. However, I'm all for optimizing those
pathways, and the query compilation cache could be a place to store
whatever intermediate caches we are able to assemble.
