In py2neo v2.0, it was possible to use a transaction to execute Cypher statements:
tx=graph.cypher.begin()
tx.append("MERGE (n:Process {proc_nm : {proc_nm}}) ON CREATE SET n.count = 1 ON MATCH SET n.count = n.count +1", {proc_nm : 'wibble'})
tx.commit
When processing complex files this allows very fast updates to be made to the Neo4J database.
In py2neo v3.0 the syntax has changed to:
graph.run(("MERGE (n:Process {proc_nm : {proc_nm}}) ON CREATE SET n.count = 1 ON MATCH SET n.count = n.count +1", {proc_nm : 'wibble'}))
This means that I can run the cypher statements singly but the performance takes a massive hit. I can write CREATE/MERGE for the Nodes and Relationships however I was hoping to not have to re-write a bunch of routines that I'm already using. What am I missing?
