Thanks for the reply Mark. So a couple of questions. When is distributed indexing going to be available on Trunk? Are there docs on it now?
I think having Roles on the shard would scratch the itch here, because as you said I could then include a role which indicated what to do with this server. My use case is actually for something outside of Solr. As of right now we are not on the latest trunk (actually a few months back I think) but could push to upgrade to it if the distributed indexing code was available today, but management may still shoot that down because of a short timeline. Suffice it to say that I'll be reading this information by another application to handle distributed indexing externally. The version that I'm working on requires that the application be responsible for performing the distribution.
