# DataX GDBWriter
|
||||
|
||||
## 1 快速介绍
|
||||
|
||||
GDBWriter插件实现了写入数据到GDB实例的功能。GDBWriter通过`Gremlin Client`连接远程GDB实例，获取Reader的数据，生成写入DSL语句，将数据写入到GDB。
|
||||
|
||||
## 2 实现原理
|
||||
|
||||
GDBWriter通过DataX框架获取Reader生成的协议数据，使用`g.addV/E(GDB___label).property(id, GDB___id).property(GDB___PK1, GDB___PV1)...`语句写入数据到GDB实例。
|
||||
|
||||
可以配置`Gremlin Client`工作在session模式，由客户端控制事务，在一次事务中实现多个记录的批量写入。
|
||||
|
||||
## 3 功能说明
|
||||
因为GDB中点和边的配置不同，导入时需要区分点和边的配置。
|
||||
|
||||
### 3.1 点配置样例
|
||||
* 这里是一份从内存生成点数据导入GDB实例的配置
|

|
||||

}
|
||||
|

```
|
||||
### 3.2 边配置样例
|
||||
* 这里是一份从内存生成边数据导入GDB实例的配置
|
||||
> **注意**
|
||||
> 下面配置导入边时，需要提前在GDB实例中写入点，要求分别存在id为`person-{{i}}`和`book-{{i}}`的点，其中i取值0~100。
|
||||
|
||||

## 4 性能报告
|
||||
### 4.1 环境参数
|
||||
GDB实例规格
|
||||
- 16core 128GB, 1TB SSD
|
||||
|
||||
DataX压测机器
|
||||
- cpu: 4 * Intel(R) Xeon(R) Platinum 8163 CPU @ 2.50GHz
|
||||
- mem: 16GB
|
||||
- net: 千兆双网卡
|
||||
- os: CentOS 7, 3.10.0-957.5.1.el7.x86_64
|
||||
- jvm: -Xms4g -Xmx4g
|
||||
|
||||
### 4.2 数据特征
|
||||
|
||||
```
|
||||
{
|
||||
id: random double(1~10000)
|
||||
from: random long(1~40000000)
|
||||
to: random long(1~40000000)
|
||||
label: random long(20000000 ~ 20005000)
|
||||
propertyKey: random string(len: 120~128)
|
||||
propertyName: random string(len: 120~128)
|
||||
}
|
||||
```
|
||||
- 点/边都有一个属性，属性key和value都是长度120~128字节的随机字符串
|
||||
- label是范围20000000 ~ 20005000的随机整数转换的字符串
|
||||
- id是浮点数转换的字符串，防止重复
|
||||
- 边包含关联起点和终点，测试边时已经提前导入twitter数据集的点数据(4200W)
|
||||
|
||||
### 4.3 任务配置
|
||||
分点和边的配置，具体配置与上述的示例配置相似，下面列出关键的差异点
|
||||
|
||||
- 增加并发任务数量
|
||||
> "channel": 32
|
||||
|
||||
- 使用session模式
|
||||
> "session": true
|
||||
|
||||
- 增加事务批量处理记录个数
|
||||
> "maxRecordsInBatch": 128
|
||||
|
||||
### 4.4 测试结果
|
||||
|
||||
点导入性能：
|
||||
- 任务平均流量： 4.07MB/s
|
||||
- 任务总计耗时： 412s
|
||||
- 记录写入速度： 15609rec/s
|
||||
- 读出记录总数： 6400000
|
||||
|
||||
边导入性能：
|
||||
- 任务平均流量： 2.76MB/s
|
||||
- 任务总计耗时： 1602s
|
||||
- 记录写入速度： 10000rec/s
|
||||
- 读出记录总数： 16000000
|
||||
|
||||
## 5 约束限制
|
||||
- 导入边记录前要求GDB中已经存在边关联的起点/终点
|
||||
- GDBWriter插件与用户查询DSL使用相同的GDB实例端口，导入时可能会影响查询性能
