I've run into this problem, and resorted to using the Gremlin/Groovy over REST (via the server-included plugin). There really isn't a way to transactionally express a conditional (or get-or-create) like that over the vanilla REST API, though I'm sure it's in the works. -- Ma

ignorance, but I've tried to do my homework. http://wiki.neo4j.org/content/Transactions#Isolation leads me to believe that maybe code like above won't work, because it only writes on condition after a read, but doesn't have a read lock. Could this be the case? and if so, is there a

Re: [Neo4j] Executing arbitrary code through REST (was: Specifying "best first" order of traverse over REST API)

Maybe the solution would be to re-run the traversal each time, and then return different slices, but that's a pretty painful tradeoff. -- Matt Luongo Co-Founder, Scholr.ly On Fri, Aug 26, 2011 at 1:12 PM, Matt Luongo wrote: > You can run the script through the Python neo4jrestclient
