主键： /Larry/Ellison

子键：/SYS

• 创新的 主键 + 子键 + 值 KV模型

• 键/值均可自定义

• 主键HASH计算为“索引”

• Java API 高效读写

Oracle NoSQL DB的数据模型和Schema 主键和次键

{ ("4c2209f9f3924d31102bd84a"), "name" : “David" }

{ ("4c2209fef3924d31102bd84b"), "x" : 3 }

{ ("4c220a42f3924d31102bd856"), "x" : 4, "j" : 1 }

Oracle NoSQL DB的数据建模 JSON 数据格式

为什么使用 Avro? 压缩，高效数据序列化

Hadoop中得到广泛使用

Schema模型 基于Avro JSON定义，可以使用DDL创建

数据模型

支持从JSON序列化/反序列化

Schema模型修改 模型修改简单方便

模型可版本话控制幵且对前端透明

{ ("4c2209f9f3924d31102bd84a"), "name" : “David" }

{ ("4c2209fef3924d31102bd84b"), "x" : 3 }

{ ("4c220a42f3924d31102bd856"), "x" : 4, "j" : 1 }

db.c1.find( { age : { $ne : 7 } } );

{ "_id" : ObjectId("4fb4af89afa87dc1bed94331"), "age" : 8, "length_1" : 30 }

{ "_id" : ObjectId("4fb4af8cafa87dc1bed94332"), "age" : 6, "length_1" : 30 }

> j = { name : “David" };

{"name" : “David"}

> db.things.save(j);

Oracle NoSQL DB的可配置持久化和一致性策略

Oracle NoSQL DB支持LOB大对象

高效存储和获取大对象

客户端使用流式接口降低内存消耗

Oracle NoSQL服务器把大对象切分成多个Chunk幵跨节点存储，降低读写延迟

• 自劢把存储使用率过高的数据均衡到其他使用率不高的节点上去

• Shard数据和复制因子保持不变

提升性能
