How would you build a high performance, semi-real-time stats service?
lsc: hm... does anyone use MySQL NDB cluster, the in memory db?  with ram prices what they are, that sort of thing sounds like the way to go.  I mean, with 64GiB ram servers being under $4K in parts these days, it seems like it might also be affordable.Of course, I haven't used MySQL ndb cluster for several years.   it seemed solid then, but I haven't used it since.
