Doesn't the fact that its writing to disk make it expensive? What exactly are you comparing them to? Since you're saying they're both cheap you're not talking about RavenDB's reads vs writes - how can they both be cheap? Without a point of reference this just sounds like marketing speak. http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment11http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment11Wed, 20 Oct 2010 14:38:42 GMTDetails :-) I guess relative to some of the other solutions raven-fast could be considered as slow, but compared to say a relational store where we have indexes and foreign keys set up and a write means validating all of these? Doesn't it depends what we are comparing against? http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment10http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment10Wed, 20 Oct 2010 09:48:14 GMTRob, Well, writes are cheap, but they still go to disk. Mongo make them very cheap because they write to memory http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment9http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment9Wed, 20 Oct 2010 09:45:03 GMTI always thought of it as "reads are cheap and writes are cheap, but you might have to wait for consistency" Whereas Mongo is fast writes, slow reads, couch is slow writes fast reads but both are consisrent-at-point-of-query Plus everything else that is different. http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment8http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment8Wed, 20 Oct 2010 09:35:12 GMTNC, I don't know about the others, but in RavenDB it's true that "reads are cheap and writes are expensive (relatively)". http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment7http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment7Wed, 20 Oct 2010 08:43:30 GMTSo based on google, MongoDB is geared more towards writing while CouchDB/RavenDB is geared more towards reading.? http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment6http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment6Wed, 20 Oct 2010 04:56:18 GMTCurious, whats the different between MongoDB vs CouchDB/RavenDB? Isn't MongoDB more popular than CouchDB? http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment5http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment5Wed, 20 Oct 2010 04:44:13 GMTConfigurator, I think he refers to this one [mail-archives.apache.org/.../...@mail.gmail.com%3E](http://mail-archives.apache.org/mod_mbox/couchdb-user/201010.mbox/%3CAANLkTinZnuW3vX9htju9Vyb=uKBVTaNeLqwMSu_PkXVJ@mail.gmail.com%3E)http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment4http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment4Tue, 19 Oct 2010 21:45:06 GMTThe link is to an archive, not a specific question. http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment3http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment3Tue, 19 Oct 2010 21:06:19 GMTBogdan, There are currently 27 people who committed to RavenDB, but I am the major committer. http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment2http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment2Tue, 19 Oct 2010 17:02:27 GMT@Ayende - Out of the curiosity, were you the only one developer for RavenDB or there were others to help you ? http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment1http://ayende.com/4666/ravendb-in-comparison-to-couchdb#comment1Tue, 19 Oct 2010 16:55:52 GMT
