I think your memory setting is wrong.
On my desktop running with 4G heap, it can handle these numbers.
Can you make sure to check neo4j-wrapper.conf and set the HEAP size to 12 or 16G
dbms.memory.heap.max_size=16000
By default the JVM only take 1G or so of heap.

Double Negation ?
r1 is never null
Add a label to n1
Use a Union
Look at the query plan with profile
Try this:
MATCH (n:`label1`:`label2`) WHERE size( (n)-[:rel1]->() ) = 0
RETURN COUNT(n) AS count;
UNION
MATCH (n:`label1`:`label2`)-[r1:rel1]->(n1:Label3) WHERE n1.`name` IN
["name1","name2"]
RET
1. Use labels
you don't need the WITH (except for LIMIT batching)
and you should be able to delete up to 1M entities per transaction with a
heap size of 4G
so you can use LIMIT 100

Richard,
I think you understood the graph data model well enough to get started, I
recommend to take the online intro course to get up to speed with the query
language.
it should be easy to get your data imported into Neo4j with LOAD CSV + MERGE
for hosting there are cloud hosting offerings for
Can you explain your use-case a bit more?
Neo4j Spatial is a GIS library for Neo4j that can be connected to GeoServer.

The optional match is like an outer join
MATCH (s:Student)
OPTIONAL MATCH (s)-[:REGISTRATIOn]->(c:Course)
WITH s, count(c) as courses
RETURN s.name, s.intelligence, courses

Can you share how the code you access the database and the error? If you
run it as a server and then access it via an http driver you can use as
many clients as you want.

Last year we had a hackathon the Sunday before. And I presented on graph
compute with Neo4j.
You can also meet me in Dresden when I'm around.
Please let me know if you want to meet. Where are you originally located?

It has, yes.
What's your use case?
Neo4j uses lucene under the hood (the history is a bit complicated). But
the upcoming version will again have fully integrated FTS within the query
language for all STARTS WITH, CONTAINS, ENDS WITH.

You can use an array property or string concat for the unique property

Matteo,
you can try:
MATCH (a:Label {id:1}),(b:Label {id:2})
WITH [ idx in range(0,size(a.prop)-1) WHERE a.prop[idx] != b.prop[idx] |
a.prop[idx] - b.prop[idx] ] as diff
SET a.diff = diff
RETURN diff, [x in diff WHERE x < 0.1] as below_treshold

Hi
Cypher avoids cycles in matched paths by following a relationship only once but
you can add additional checks.
In the Java Traversal API there is more fine grained control of uniqueness in a
path.

Sure you have to change your embedded instance to 2.3.2 too
Otherwise you get version conflicts as you gto.

I just saw that you have much more RAM available than you use. You're running
with 1G heap only but 4G of page-cache for the DB
You should adapt the latter to your db-size and up the heap to 4 or 8 G
depending on your use-case.
Also if you could share your concrete queries that would be more hel
do you think you could reproduce it?
Could it be that one of your rel-types has an "invisible" leading or trailing
whitespace?
