Hi guys, I've installed neo4j with pacman and am able to run the web console, however when I try to just start the server (either with neo4j start or systemctl start neo4j.service) it says it failed to start within the timeout period, but it doesn't wait for the full timeout period. Looking at

Right then you have to lable your nodes like match (n) where n.crime_type SET n:Crime; and then create the index: create index on :Crime(crime_type); On Sun, Oct 5, 2014 at 8:53 PM, Mohana Krishna, IIT Bombay, India < mohana...@gmail.com> wrote: > Michael, > > Can you please give me the fu

tx.close() will either commit your transaction if you called tx.success(), or roll it back if you either did not call tx.success() or called tx.failure(). When you start a new transaction without closing the one you already have, the new transaction will become a sub-transaction of the outer one

[Neo4j] should Transaction.close() be called for batch jobs?

2014-10-05 Thread Frandro
The following code newly begins transaction each 1000 batch job. Is the following code correct? Do I have to invoke the tx.close() method each 1000 batch job in the middle? It seems there's no problem without calling the method. What are success() and close() for? It's confusing. Transaction t
