I am very surprised this causes "issues"... The document is identical in every respect... Why does it matter if I receive another copy of an identical document? Hmmmmm.... http://ayende.com/150529/transitive-replication-in-ravendb#comment9http://ayende.com/150529/transitive-replication-in-ravendb#comment9Sat, 24 Dec 2011 05:25:09 GMTI showed you Correspondence while you were in Dallas. The way it solves the problem is simple. Every object is immutable. And any two objects with exactly the same values are considered to be the same object. The object can come from multiple directions and it won't be a duplicate.http://ayende.com/150529/transitive-replication-in-ravendb#comment8http://ayende.com/150529/transitive-replication-in-ravendb#comment8Sat, 24 Dec 2011 01:58:21 GMTA little additional context, the transitive replication was needed to support blue/green deployment (in my case, at least). While the replication needed to happen across an arbitrary number of servers, only 2 of those servers would ever actually exist at any one point in time.http://ayende.com/150529/transitive-replication-in-ravendb#comment7http://ayende.com/150529/transitive-replication-in-ravendb#comment7Fri, 23 Dec 2011 17:06:47 GMTs/whatever/whether/g where 'g' means in all your other posts, too...http://ayende.com/150529/transitive-replication-in-ravendb#comment6http://ayende.com/150529/transitive-replication-in-ravendb#comment6Fri, 23 Dec 2011 13:59:56 GMTValeriu, no, it isn't. I just updated the blog software, and it might be related to that, I'll check it next week.http://ayende.com/150529/transitive-replication-in-ravendb#comment5http://ayende.com/150529/transitive-replication-in-ravendb#comment5Fri, 23 Dec 2011 11:56:32 GMTValeriu, no, it isn't.

One of the words is the real captcha the other is a word that you are helping to decode. But you are right they are a pita.http://ayende.com/150529/transitive-replication-in-ravendb#comment2http://ayende.com/150529/transitive-replication-in-ravendb#comment2Fri, 23 Dec 2011 11:30:45 GMTI wonder if these customers REALLY needed bi-directional replication. This is not a very common setup and chances are they could have designed it in a better way - witho only one direction of replication and without cycles. Maybe this should be handled like a pub/sub message distribution in message bus - each document type has its master/origin database where it can be inserted and updated and all other databases are only allowed to take read-only replicas of that document from the master. And a 'slave' for one document type can be a master of another type. PS your captchas are barely readable or I'm just a computer programmed to consider itself a humanhttp://ayende.com/150529/transitive-replication-in-ravendb#comment1http://ayende.com/150529/transitive-replication-in-ravendb#comment1Fri, 23 Dec 2011 10:50:56 GMT
