This sample project demonstrates sharding technique with RavenDB. It contains source code and three RavenDB servers (binaries only) which store data in-memory. Every restart of the servers clears the databases.
This sample uses RavenDB servers from the build 800 which is available from http://builds.hibernatingrhinos.com/builds/RavenDB
Config file of every server has been modified to use specific IP (127.0.0.1), ports (8081-8083) and hold data in-memory. Also anonymous user has ALL access rights.
To see it working you can
Start RavenDB servers, you can do so by running a cmd file \tools\RavenDB-Build-800\Just-Servers\Start.cmd This shall open three console application, one for each RavenDB server
[a] Either open solution in Visual Studio 2010 and run the project
or [b] Run the binary client directly from \bin\RavenDbSharding.exe
Take a look at the RavenDB servers to see which request goes to which server. Users are stored on the following shards: Users with id 1 - 10 are stored in shard "user_1_10" Users with id 11 - 20 are stored in shard "user_10_20" Users with id 21 - 30 are stored in shard "user_20_30"
