Replication in RavenDb is pretty fekin sweet. I helped Oren by submitting bugs and testing it out in sonatribe dev by pushing it in a real world usage scenario. One of the features I asked about was the ability to filter out parts of the namespace for replication – instead of the ‘all or nothing’ approach used by default. Oren (as you’d expect) simply replied with a request for a patch. So here is my patch.
My fork is here: https://github.com/wayne-o/ravendb
Basically – my aim is to allow the developer to set replication filters – so only a part of a namespace is replicated – rather than the whole db. To do this I’ve added a ReplicationPredicate class in the Raven.Bundles.Replication.Data namespace. this is used when initialising the db:
it’s a work in progress but i’m finding it hard to get the time to commit to it due to the new baby. if anyone fancies lending a hand – there’s a test in the SimpleReplication.cs file Can_filter_replication_using_replication_predicates
