我使用的是neo4j 1.9.4嵌入式模型。执行短路查询（50万个节点和600万个关系）时花了太长时间。我阅读了手册并找到了两个属性：
1. conf/neo4j-server.properties
org.neo4j.server.webserver.limit.executiontime=1000
2. conf/neo4j.properties
execution_guard_enabled=true
但问题是，似乎没有＆＃39; neo4j-server.properties＆＃39;嵌入式模型中的文件。如何设置？或者“超时”＆＃39;嵌入式模型不支持属性吗？
请帮忙。非常感谢！
代码：
PathFinder<Path> finder = GraphAlgoFactory.shortestPath(Traversal
.expanderForTypes(RelationshipTypes.r01, Direction.BOTH)
.add(RelationshipTypes.r02, Direction.BOTH), 10);
paths = finder.findAllPaths(node1, node2);
for (Path shortestPath : paths) {
List<NodeBean> nodeList = new ArrayList<NodeBean>();
List<String> rList = new ArrayList<String>();
... ...
}

Direction.BOTH表示它是圆圈。
您的MMIO设置应该更大（更接近文件大小）， 你的堆也可能（因为它包括Windows上的mmio部分 - ＆gt;至少12G到16G堆）。
您没有共享messages.log中有关堆大小的指示。
neostore.nodestore.db.mapped_memory=500M
neostore.relationshipstore.db.mapped_memory=6G
neostore.propertystore.db.mapped_memory=1G

如果您仍然运行企业，则应使用：
cache_type=hpc
或
cache_type=none
对于Guard，除了设置你已经拥有的配置外，添加它的代码是这样的：
((GraphDatabaseAPI)graphDB).getDependencyResolver().resolveDependency(Guard.class);
guard.startTimeout(timeLimit);
guard.startOperationsCount(maxOps);
try {
return doOperation();
} catch (GuardException e) {
LOG.warn("Aborting Operation ");
throw new RuntimeException(e);
} finally {
guard.stop();
}
