I’ve encountered a “GC overhead limit exceeded” problem in Neo4j Java API.

Hi all,
I'm using neo4j.2.3.0.
I'm running some experiments (over ~1000 graph queries) on the Neo4j Java
API. I don't use the cypher for that. So, I have my own algorithm. After
running around 100/200 queries, I'm getting the "GC Overhead Limit
Exceeded". I think there is something wrong with "

When I see inside of
the index directory it has just "segments_1" and "segments.gen". How can I
make some index over the labels of a created graph?

Hi Dear Michael,
Sorry, I cannot understand this:
"You are not supposed to set the pagesize
And leave off that cache capacity"
It means that I should remove those lines related to set the pageSize and
cacheSize?
Thanks.

Hi,
I want to use Neo4j in a streaming graph database which by the time
nodes/edges are inserted/removed.
However, as you know "dataGraph.createNode()" and "srcNode
.createRelationshipTo(destNode, RelationshipType.withName(relationship))"
are slow operations.
How I can simulate streaming graph
Dear programmers,
Hi,
I have a requirement to have all node Id's in the graph database started
from 0[max Number Of Nodes]. I won't add/remove any node after I create
the initial graph database. Right now, I have a graph database that is not
like that so node Id's are like
Dear all Neo4j Programmers,
Hi,
I am a Mac user having Neo4j 3.0 on my laptop. I want to use "neo4j-import"
as I've used it in previous versions to import graphs.
I've found it in "Application" directory. Then, by "showing package
content", I've reached to the Neo4j-import.
However, when I

I've removed the label folder and run it again. I was watching the folder.
it first created a lot of files then removed all of them and created just
14 items including write.lock and segments_1.

Hi,
I've imported a huge dataset into Neo4j. 33M nodes and 144M relationships.
Thanks to Neo4j makers, "neo4j-importer" was very efficient. However, I'm
getting (Too many open files) errors.
...
Caused by: java.nio.file.FileSystemException:
/fastscratch/mnamaki/idsForExp/idsAttackDB/schema/
In total 110 distinct labels for all nodes. So, each label has a large
number of corresponding nodes in datagraph.
The problem was originally from my code.
