# 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
```json
{
"job": {
"setting": {
"speed": {
"channel": 1
}
},
"content": [
{
"reader": {
"name": "streamreader",
"parameter": {
"column" : [
{
"random": "1,100",
"type": "double"
},
{
"random": "1000,1200",
"type": "long"
},
{
"random": "60,64",
"type": "string"
}
],
"sliceRecordCount": 1000
}
},
"writer": {
"name": "gdbwriter",
"parameter": {
"host": "gdb-endpoint",
"port": 8182,
"username": "root",
"password": "***",
"writeMode": "INSERT",
"labelType": "VERTEX",
"label": "${1}",
"idTransRule": "none",
"session": true,
"maxRecordsInBatch": 64,
"column": [
{
"name": "id",
"value": "${0}",
"type": "string",
"columnType": "primaryKey"
},
{
"name": "vertex_propKey",
"value": "${2}",
"type": "string",
"columnType": "vertexProperty"
}
]
}
}
}
]
}
}
```
### 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。
```json
{
"job": {
"setting": {
"speed": {
"channel": 1
}
},
"content": [
{
"reader": {
"name": "streamreader",
"parameter": {
"column" : [
{
"random": "100,200",
"type": "double"
},
{
"random": "1,100",
"type": "long"
},
{
"random": "1,100",
"type": "long"
},
{
"random": "2000,2200",
"type": "long"
},
{
"random": "60,64",
"type": "string"
}
],
"sliceRecordCount": 1000
}
},
"writer": {
"name": "gdbwriter",
"parameter": {

"idTransRule": "none",
"srcIdTransRule": "labelPrefix",
"dstIdTransRule": "labelPrefix",
"srcLabel":"person-",
"dstLabel":"book-",
"session":false,
"column": [
{
"name": "id",
"value": "${0}",
"type": "string",
"columnType": "primaryKey"
},
{
"name": "id",
"value": "${1}",
"type": "string",
"columnType": "srcPrimaryKey"
},
{
"name": "id",
"value": "${2}",
"type": "string",
"columnType": "dstPrimaryKey"
},
{
"name": "edge_propKey",
"value": "${4}",
"type": "string",
"columnType": "edgeProperty"
}
]
}
}
}
]
}
}
```

## 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
