Hi,
I am a newbie of Neo4j and I am currently doing some tests.
I have installed Neo4j2.1.1 enterprise into a VM equipped with an IntelXeon
2CPU @2.67GHz and 8GB RAM on Windows 7 64bit and Java8 64bit.
I am working with the Neo4jShell from localhost and I have set some jvm
options (EXTRA_JVM_ARGUMENTS=-Xms2000m -Xmx5000m) into Neo4jShell.bat
I have successfully load 2.000.000 nodes (with 12 simple properties each)
from a CSV file using the LOAD CSV command in 5 minutes.
I have also set 2 index on two properties of these nodes.
Now I want to delete all of them using Cypher with the statement "MATCH
(p:Label) DELETE p" but I get this java exception:
neo4j-sh (?)$ match (p:Label) delete p;
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit
