2,关于blueprints

这里写图片描述
Blueprints是一组针对属性图数据模型的接口、实现、测试套件,有些类似于JDBC,不同之处在于Blueprints是针对图形数据库的。Blueprints提供了一组通用的接口,允许开发者在他们的图形数据库后端即插即用。
这里写图片描述
这个图表示了blueprints的位置,在最底层,决定数据存储。

https://github.com/tinkerpop/blueprints/wiki

对数据进行CRUD没有问题。

4,总结

代码就一个pom和java类,非常简单的就把图的数据存储到了数据库中。
存储到mysql里面类似,需要修改下jdbc连接即可。
如果作为业务服务,现在的代码再加点就基本满足了。
虽然数据库存储的比neo4j,solr等稍微慢点,但是运维成本低,数据库可以做主从复制,保护数据,同时多个服务访问一个数据库也可以解决单点服务问题。
数据库的优化非常多,非常方便,同时索引速度也挺快的。这个存储的是关系,一般情况先数据不太大,再使用mycat进行分库分表就可以扩展了。
