Most of the map/reduce implementations are about distributing the work load and scheduling it. None of them really deal with the notion of updatable map/reduce results." You might want to take a look at Percolator, it's Google enhancement to Map/Reduce to solve this exact issue. I.e. so it doesn't have to re-create it's index from scratch every 2 weeks, it can do incremental updates. See http://www.theregister.co.uk/2010/09/24/google_percolator/ and http://static.googleusercontent.com/external_content/untrusted_dlcp/research.google.com/en//pubs/archive/36726.pdf It might have some ideas that could be used in RavenDBhttp://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment9http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment9Fri, 17 Aug 2012 16:51:05 GMTBrian, That code is there to make my life easier. This project is there as a POC. I am not going to worry about it.http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment8http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment8Mon, 13 Aug 2012 13:01:40 GMTOren, then might I suggest you at least put some sanity check around that block. Even though this is not production code, that's just leaving a loaded gun lying around (it's irresponsible coding and if you were reviewing any code that did this I'll bet you'd have blasted the author, too).http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment7http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment7Mon, 13 Aug 2012 12:59:52 GMTStarfish, Not outward facing, not from this.http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment6http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment6Mon, 13 Aug 2012 11:44:21 GMTI trust there are no "breaking" changes?http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment5http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment5Mon, 13 Aug 2012 11:40:43 GMTBrian, Yes... ? This is there to make sure that we clear old results from the previous run.http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment4http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment4Sat, 11 Aug 2012 16:29:46 GMTOne shouldn't run this exe from C:/ with admin privileges... lolhttp://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment3http://ayende.com/157954/the-next-big-thing-in-ravendb-1-2#comment3Fri, 10 Aug 2012 21:22:54 GMTTake a look at this: https://github.com/nathanmarz/storm/ Maybe is not what you are looking for, or in the same language for that matter, but maybe it can give you some ideas...
