I understand that this could be handy for bulk inserts, but wouldn't the majority of inserts be 1 at a time? It's pretty annoying to have my Id's be 1, 32, 64, etc. And maybe I just need to look into this more before getting too frustrated, and maybe there's a simply way to do something like "id = getmaxid +1"http://ayende.com/154337/ravendb-self-optimizing-ids#comment14http://ayende.com/154337/ravendb-self-optimizing-ids#comment14Tue, 24 Apr 2012 16:19:02 GMTJesse, Huh? How did you get to that? What we are actually doing is optimizing ourselves on demand, so if you are inserting bulk data, we would reduce the number of requests to the serverhttp://ayende.com/154337/ravendb-self-optimizing-ids#comment13http://ayende.com/154337/ravendb-self-optimizing-ids#comment13Tue, 24 Apr 2012 15:51:28 GMTSo basically, you have to insert 32 documents at a time, and that is the only option other than looking at the last Id, and manually updating the Id integer for every document? Or you can query the whole collection for the last Id.. that's gotta be a better way.http://ayende.com/154337/ravendb-self-optimizing-ids#comment12http://ayende.com/154337/ravendb-self-optimizing-ids#comment12Tue, 24 Apr 2012 15:34:03 GMTWow, Raven learns from recent usage patterns. Very cool.http://ayende.com/154337/ravendb-self-optimizing-ids#comment11http://ayende.com/154337/ravendb-self-optimizing-ids#comment11Tue, 27 Mar 2012 20:56:53 GMTMauro, I do not (yet) have replication setups with RavenDB. Can a slave in RavenDB also do CUD? At this moment we have a few MSSQL DB's which have merge replication. These are master/master../master types which can also work in a disconnected enviroment (nice with crappy connections) and thus on different physical locations. Althought it works nice it is far from zero config and sometimes high maintenance. http://ayende.com/154337/ravendb-self-optimizing-ids#comment10http://ayende.com/154337/ravendb-self-optimizing-ids#comment10Tue, 27 Mar 2012 13:58:38 GMTEdward, I think it's a bad idea to have a multi-master db (where multi >2), I'm trying a master-multislave configuration with failover insteadhttp://ayende.com/154337/ravendb-self-optimizing-ids#comment9http://ayende.com/154337/ravendb-self-optimizing-ids#comment9Tue, 27 Mar 2012 12:31:44 GMTEdward, Yes, that is the idea. Or you use a guid, but that isn't as readable.http://ayende.com/154337/ravendb-self-optimizing-ids#comment8http://ayende.com/154337/ravendb-self-optimizing-ids#comment8Tue, 27 Mar 2012 11:13:51 GMTIts a master/master, could also be a master/master/master. You mean users/serverId/1234 ?http://ayende.com/154337/ravendb-self-optimizing-ids#comment7http://ayende.com/154337/ravendb-self-optimizing-ids#comment7Tue, 27 Mar 2012 10:15:39 GMTEdward, Is it a master / master? Master / slave? If it is master slave, it is easy. If it is master / master, you probably was to add the write server id to the id, to ensure uniqueness, something like users/1/1234http://ayende.com/154337/ravendb-self-optimizing-ids#comment6http://ayende.com/154337/ravendb-self-optimizing-ids#comment6Tue, 27 Mar 2012 10:08:56 GMTWhat would be the recommended way for generating human readable id's for a replicated enviroment?http://ayende.com/154337/ravendb-self-optimizing-ids#comment5http://ayende.com/154337/ravendb-self-optimizing-ids#comment5Tue, 27 Mar 2012 09:32:58 GMTEdward, You generally do not generate ids in this manner in a replicated env.http://ayende.com/154337/ravendb-self-optimizing-ids#comment4http://ayende.com/154337/ravendb-self-optimizing-ids#comment4Tue, 27 Mar 2012 08:56:17 GMTDoes this generation of id's not conflict in a replicated enviroment?http://ayende.com/154337/ravendb-self-optimizing-ids#comment3http://ayende.com/154337/ravendb-self-optimizing-ids#comment3Mon, 26 Mar 2012 17:43:58 GMTShane, Guid aren't human readable.http://ayende.com/154337/ravendb-self-optimizing-ids#comment2http://ayende.com/154337/ravendb-self-optimizing-ids#comment2Mon, 26 Mar 2012 14:56:05 GMTWhat was the reason you didn't go with Comb Guid which wouldn't have the same problem? Performance of some kind or just personal preference?http://ayende.com/154337/ravendb-self-optimizing-ids#comment1http://ayende.com/154337/ravendb-self-optimizing-ids#comment1Mon, 26 Mar 2012 14:52:07 GMT
