之前体验了下tinkerpop的console服务。
存储数据，然后进行查询数据。

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。

这个图表示了blueprints的位置，在最底层，决定数据存储。

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

其中blueprints支持的存储：
TinkerGraph (TinkerGraph)
Neo4j Implementation (Neo4jGraph)
Neo4jHA Implementation (Neo4jHaGraph)
Neo4jBatch Implementation (Neo4jBatchGraph)
Sail Implementation (SailGraph)
Sparksee Implementation (SparkseeGraph)
Rexster Implementation (RexsterGraph)
Accumulo Implementation (AccumuloGraph – 3rd party – implements Blueprints 2.4.0)
ArangoDB Implementation (ArangoDBGraph – 3rd party – implements Blueprints 2.3.0)
Bitsy (BitsyGraph – 3rd party – implements Blueprints 2.4.0)
Bigdata (BigdataGraph – 3rd party – implements Blueprints 2.5.0)
FluxGraph - Datomic Implementation (FluxGraph – 3rd party – implements Blueprints 2.1.0)
FoundationDB Implementation (FoundationDBGraph – 3rd party – implements Blueprints 2.4.0)
InfiniteGraph Implementation (IGGraph – 3rd party – implements Blueprints 2.1.0)
JPA Implementation (JpaGraph – 3rd party – implements Blueprints 2.5.0)
MongoDB Implementation (MongoDBGraph – 3rd party – implements Blueprints 2.3.0)
Oracle NoSQL Implementation (KVGraph – 3rd party – implements Blueprints 2.1.0)
OrientDB Implementation (OrientGraph – 3rd party – implements Blueprints 2.4.0)

对数据进行CRUD没有问题。

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。
