neo4j 企业版 最新版 neo4j-enterprise-4.2.1下载
企业版和社区版对比：
社区版和企业版有什么区别。其实他们在功能上没有本质区别。主要区别在如下几点：
1、容量：社区版最多支持 320 亿个节点、320 亿个关系和 640 亿个属性，而企业版没有这个限制；
2、并发：社区版只能部署成单实例，不能做集群。而企业版可以部署成高可用集群或因果集群，从而可以解决高并发量的问题；
3、容灾：由于企业版支持集群，部分实例出故障不会影响整个系统正常运行；
4、热备：社区版只支持冷备份，即需要停止服务后才能进行备份，而企业版支持热备，第一次是全量备份，后续是增量备份；
5、性能：社区版最多用到 4 个内核，而企业能用到全部内核，且对性能做了精心的优化；
6、支持：企业版客户能得到 5X10 电话支持（Neo4j 美国电话、邮件，微云数聚电话、微信、邮件）；
6、插件：还有企业版可以使用Bloom、ETL这些工具，社区版不支持
关于社区版与企业版的性能对比，最近我做了一个 对比试验，企业版的性能是社区版的 2~4 倍，我将另外发帖将对比结果分享给大家。
