Hi Pieter, Jim recently added support for paging in the Neo4j server for traversals,
For Cypher, there is SKIP and LIMIT, together acting as a kind of paging system, but executing the query again (just giving you a different chunk of the result), so I am not sure that works for your case. http://docs.neo4j.org/chunked/snapshot/cypher-query-lang.html. Gremlin supports similar things. Also, given that you have millions of relationships on one node, could you think of some way of doing some in-graph or other indexing on these structures? Can you break up the relationships along one or two properties like time or a scalar range? Otherwise, that query seems to be quite expensive. Do you need all results?
