Question

我对neo4j很新，面对以下问题。执行批量导入（Micheal Hunger - 批量导入程序）命令时，我收到有关cache_type设置的错误。它建议使用gcr设置，但这些设置仅在企业版中提供。

非常感谢帮助，谢谢。

系统信息 win7 32bit 4G RAM（3G可用），jre7，neo4j-community-1.8.2

数据:(非常小的测试数据） nodes.csv（制表符分隔）13个节点 rels.csv（制表符分隔）16关系

执行和错误：

C：\ Daten \ Studium \ LV HU Berlin \ SS 2013 \ Datamanagement and BI \ Neuer Ordner＆gt; java -server -Xmx1G -jar target \ batch-import-jar-with-dependencies.jar target \ db nodes.csv rels.csv

使用现有配置文件

Batch.properties：

dump_configuration=false

cache_type=none

use_memory_mapped_buffers=true
neostore.propertystore.db.index.keys.mapped_memory=5M
neostore.propertystore.db.index.mapped_memory=5M
neostore.nodestore.db.mapped_memory=200M
neostore.relationshipstore.db.mapped_memory=500M
neostore.propertystore.db.mapped_memory=200M
neostore.propertystore.db.strings.mapped_memory=200M

遇到了和你一样的问题，我改变了batch.properties

中的行

cache_type=none到cache_type=gcr并且它有效。不确定速度如何变化。不确定为什么其他选项none，soft，weak，strong无效。也许迈克尔可以给出答案吗？
