Why do you want to do it?
Did you check the bin/neo4j startup script for the required parameters?
I usually just use bootstrapper.start()

Yep, exactly.
It was not an issue before but the implementation changed and there were
some places that have not yet been fully converted.
That's why you see a slow-down if both the in-transaction-state as well as
the on-disk/persisted index state have to be consulted.
Will def. be fixed in 2.1
Hello
I run the following command in neo4j using Cypher:
*MATCH (a:User), (b:User)*
*WHERE a.id = 1 AND b.id = 2*
*merge (a)-[r:FOLLOW]-(b) ON CREATE SET a.follow = a.follow+1, b.followed
= b.followed+1*
*RETURN r*
Is it possible that the counter follow or followed is not updated?
I mean partial
I've just found out that there is a cap on relationships of around 34
billion:
http://docs.neo4j.org/chunked/snapshot/capabilities-capacity.html#capabilities-data-size
Which is fair enough, but assuming I could work within this limit do I
still have a problem?

The limit will be raised substantially with version 2.1 which is worked on
during spring 2014. From 35 bits to 38-42 bits (not sure atm).
How did you add the index?
create index on :Card(id);
or
create constraint on (c:Card) assert c.id is unique;
?
It should just take a few milliseconds to
Works for me, if you created both user nodes with initial properties
create (:User {id:1,follow:0, followed:0})
otherwise you have to adapt for null values:
*MATCH (a:User), (b:User)*
*WHERE a.id http://a.id/ = 1 AND b.id http://b.id/ = 2*
*merge (a)-[r:FOLLOW]-(b) ON CREATE SET a.follow =
Yes, the properties of follow and followed default to 0, so I created them.
But my question about the transaction

Recreate the nodes in auto index mode resolves this.

As you have this in a loop, that will be a lot of network traffic, causing
the slowness you have observed.
For this kind of usage, you are best to
It should not be making a new HTTP call each time. You can see if that is
the case by putting an echo statement in the Transport object's
'makeRequest' method.
If you file this as an issue in the neo4jphp github repo, I will take a
look at it.

Hi all,
I wanted to build some tests to do create statements. However I don't want
it to build out anything. Is there any endpoint that will toss any
transaction you throw at it but respond back with the proper notification?
(such as 1 node created, 1 relationship created)

I recently tried to use Neo4j. The biggest problem I have is the docs not

one. The 2.0 Cheat-Sheet is actually there, if one handles the url

You can just rollback the tx if you use the transactional endpoint.
i.e. DELETE /db/data/transaction/tx-id

You definitely need a server between you and the graph.
As for a choice of tech well that would depend on your preference, you can
use almost any language because you can hit the REST endpoint to query the
