For example, say I'm building a trading application that does "what-if" analysis on a potential transaction. The trader may want to create several "what-if" scenarios and run it...]]> Sun, 25 Sep 2011 10:30:14 -0400 Sun, 25 Sep 2011 10:30:14 -0400 Sun, 25 Sep 2011 10:30:14 -0400 Sep 25, 2011 peter lin 0 Disagree http://www.theserverside.com/discussions/thread.tss?thread_id=63035 Caching live-data could be an absolutely correct decision and it's largely depends on the overall system design. Broad statements like that are simple misleading. Cache vs. data-grid vs in-memory data grid is just a hair splitting - these terms are...]]> Sat, 24 Sep 2011 14:56:13 -0400 Sat, 24 Sep 2011 14:56:13 -0400 Sat, 24 Sep 2011 14:56:13 -0400 Sep 24, 2011 Nikita Ivanov 0 Caches: an unpopular opinion, explained... http://www.theserverside.com/discussions/thread.tss?thread_id=63035 Band aids are excellent solutions to bloody problems.

One such bloody problem is latency, for which caches is a cheap, simple and fantastically efficient solution.

Be pragmatic, dudes, not stupid.

If they didn't cache live data, their performance would be horrible -- and you can force them into such a mode by turning off all of the CPU caches...]]> Sat, 24 Sep 2011 11:00:14 -0400 Sat, 24 Sep 2011 11:00:14 -0400 Sat, 24 Sep 2011 11:00:14 -0400 Sep 24, 2011 Cameron Purdy 0 Yep, I can see that. http://www.theserverside.com/discussions/thread.tss?thread_id=63035 I didn't see Ted at NFJS, but I can certainly see him saying this - caches for live data are a bandaid worse than the original problem. Fix the problem, not the symptom! This stuff is actually pretty well known in the high perf arena, I just catch...]]> Fri, 23 Sep 2011 17:20:31 -0400 Fri, 23 Sep 2011 17:20:31 -0400 Fri, 23 Sep 2011 17:20:31 -0400 Sep 23, 2011 Joseph Ottinger 0 Caches: an unpopular opinion, explained... http://www.theserverside.com/discussions/thread.tss?thread_id=63035 Ted Neward said essentially this at the NFJS expert panel.  When confronted with a performance problem, everyone's first instinct is to say, "Oo!  We'll cache .", when it is really more or less a bandaid.  (Note I'm paraphrasing Ted...]]> Fri, 23 Sep 2011 16:59:22 -0400 Fri, 23 Sep 2011 16:59:22 -0400 Fri, 23 Sep 2011 16:59:22 -0400 Sep 23, 2011 Michael Campbell 1 Caches: an unpopular opinion, explained... http://www.theserverside.com/discussions/thread.tss?thread_id=63035 In his enigmastation.com blog, Joseph Ottinger sets the record straight on why caches are not always the right solution to a performance problem, especially when it comes to live data.
