Hi, Is Jim's paging support in 1.4 or shall I checkout a snapshot to have a look at it?
Regarding the millions of relationships, it is for now more of a generic question for a framework we are working on. Paging almost always becomes a issue. Certainly we try avoid such relationships. Yes we can almost always think of a way to index the relationship, but I do not quite understand how in-graph indexing will help? Will neo4j traverser be able to hit such a index and page the result?
