Last time i checked, neo4j REST API had a really limited support for transactions ( no way to have multiple request be part of a single transaction). Since go doesn't have a native client, i wouldn't use this combo for neo4j has my primary db.

Neo4j's streaming Cypher HTTP Endpoint (since Sept 2013) is fully transactional even accross requests, see http://neo4j.com/docs/stable/rest-api-transactional.html

Cool ! thanks for the info. I'll check that.
