# DataX GDBReader
|
||||
|
||||
## 1. 快速介绍
|
||||
|
||||
GDBReader插件实现读取GDB实例数据的功能，通过`Gremlin Client`连接远程GDB实例，按配置提供的`label`生成查询DSL，遍历点或边数据，包括属性数据，并将数据写入到Record中给到Writer使用。
|
||||
|
||||
## 2. 实现原理
|
||||
|
||||
GDBReader使用`Gremlin Client`连接GDB实例，按`label`分不同Task取点或边数据。
|
||||
单个Task中按`label`遍历点或边的id，再切分范围分多次请求查询点或边和属性数据，最后将点或边数据根据配置转换成指定格式记录发送给下游写插件。
|
||||
|
||||
GDBReader按`label`切分多个Task并发，同一个`label`的数据批量异步获取来加快读取速度。如果配置读取的`label`列表为空，任务启动前会从GDB查询所有`label`再切分Task。
|
||||
|
||||
## 3. 功能说明
|
||||
|
||||
GDB中点和边不同，读取需要区分点和边点配置。
|
||||
|
||||

# KingbaseesReader 插件文档
|
||||
|
||||
|
||||
___
|
||||
|
||||
|
||||
## 1 快速介绍
|
||||
|
||||
KingbaseesReader插件实现了从KingbaseES读取数据。在底层实现上，KingbaseesReader通过JDBC连接远程KingbaseES数据库，并执行相应的sql语句将数据从KingbaseES库中SELECT出来。
|
||||
|
||||
## 2 实现原理
|
||||
|
||||
简而言之，KingbaseesReader通过JDBC连接器连接到远程的KingbaseES数据库，并根据用户配置的信息生成查询SELECT SQL语句并发送到远程KingbaseES数据库，并将该SQL执行返回结果使用DataX自定义的数据类型拼装为抽象的数据集，并传递给下游Writer处理。
|
||||
|
||||
对于用户配置Table、Column、Where的信息，KingbaseesReader将其拼接为SQL语句发送到KingbaseES数据库；对于用户配置querySql信息，KingbaseesReader直接将其发送到KingbaseES数据库。
|
||||
|
||||
|
||||
## 3 功能说明
|
||||
|
||||
### 3.1 配置样例

}
|
||||
```
|
||||
|
||||
|
||||
### 3.2 参数说明
|
||||
|
||||
* **jdbcUrl**
|
||||
|
||||
* 描述：描述的是到对端数据库的JDBC连接信息，使用JSON的数组描述，并支持一个库填写多个连接地址。之所以使用JSON数组描述连接信息，是因为阿里集团内部支持多个IP探测，如果配置了多个，KingbaseesReader可以依次探测ip的可连接性，直到选择一个合法的IP。如果全部连接失败，KingbaseesReader报错。 注意，jdbcUrl必须包含在connection配置单元中。对于阿里集团外部使用情况，JSON数组填写一个JDBC连接即可。
|
||||
|
||||
jdbcUrl按照KingbaseES官方规范，并可以填写连接附件控制信息。具体请参看[KingbaseES官方文档](https://help.kingbase.com.cn/doc-view-5683.html)。
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **username**
|
||||
|
||||
* 描述：数据源的用户名 <br />
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **password**
|
||||
|
||||
* 描述：数据源指定用户名的密码 <br />
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **table**
|
||||
|
||||
* 描述：所选取的需要同步的表。使用JSON的数组描述，因此支持多张表同时抽取。当配置为多张表时，用户自己需保证多张表是同一schema结构，KingbaseesReader不予检查表是否同一逻辑表。注意，table必须包含在connection配置单元中。<br />
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **column**
|
||||
|
||||
* 描述：所配置的表中需要同步的列名集合，使用JSON的数组描述字段信息。用户使用\*代表默认使用所有列配置，例如['\*']。
|
||||
|
||||
支持列裁剪，即列可以挑选部分列进行导出。
|
||||
|
||||
支持列换序，即列可以不按照表schema信息进行导出。
|
||||
|
||||
支持常量配置，用户需要按照KingbaseES语法格式:
|
||||
["id", "'hello'::varchar", "true", "2.5::real", "power(2,3)"]
|
||||
id为普通列名，'hello'::varchar为字符串常量，true为布尔值，2.5为浮点数, power(2,3)为函数。
|
||||
|
||||
**column必须用户显示指定同步的列集合，不允许为空！**
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **splitPk**
|
||||
|
||||
* 描述：KingbaseesReader进行数据抽取时，如果指定splitPk，表示用户希望使用splitPk代表的字段进行数据分片，DataX因此会启动并发任务进行数据同步，这样可以大大提供数据同步的效能。
|
||||
|
||||
推荐splitPk用户使用表主键，因为表主键通常情况下比较均匀，因此切分出来的分片也不容易出现数据热点。
|
||||
|
||||
目前splitPk仅支持整形数据切分，`不支持浮点、字符串型、日期等其他类型`。如果用户指定其他非支持类型，KingbaseesReader将报错！
|
||||
|
||||
splitPk设置为空，底层将视作用户不允许对单表进行切分，因此使用单通道进行抽取。
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：空 <br />
|
||||
|
||||
* **where**
|
||||
|
||||
* 描述：筛选条件，KingbaseesReader根据指定的column、table、where条件拼接SQL，并根据这个SQL进行数据抽取。在实际业务场景中，往往会选择当天的数据进行同步，可以将where条件指定为gmt_create > $bizdate 。注意：不可以将where条件指定为limit 10，limit不是SQL的合法where子句。<br />
|
||||
|
||||
where条件可以有效地进行业务增量同步。 where条件不配置或者为空，视作全表同步数据。
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **querySql**
|
||||
|
||||
* 描述：在有些业务场景下，where这一配置项不足以描述所筛选的条件，用户可以通过该配置型来自定义筛选SQL。当用户配置了这一项之后，DataX系统就会忽略table，column这些配置型，直接使用这个配置项的内容对数据进行筛选，例如需要进行多表join后同步数据，使用select a,b from table_a join table_b on table_a.id = table_b.id <br />
|
||||
|
||||
`当用户配置querySql时，KingbaseesReader直接忽略table、column、where条件的配置`。
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **fetchSize**
|
||||
|
||||
* 描述：该配置项定义了插件和数据库服务器端每次批量数据获取条数，该值决定了DataX和服务器端的网络交互次数，能够较大的提升数据抽取性能。<br />
|
||||
|
||||
`注意，该值过大(>2048)可能造成DataX进程OOM。`。
|
||||
|
||||
* 必选：否 <br />

### 3.3 类型转换
|
||||
|
||||
目前KingbaseesReader支持大部分KingbaseES类型，但也存在部分个别类型没有支持的情况，请注意检查你的类型。
|
||||
|
||||
下面列出KingbaseesReader针对KingbaseES类型转换列表:
|
||||
|
||||
|
||||
| DataX 内部类型| KingbaseES 数据类型 |
|
||||
| -------- | ----- |
|
||||
| Long |bigint, bigserial, integer, smallint, serial |
|
||||
| Double |double precision, money, numeric, real |
|
||||
| String |varchar, char, text, bit, inet|
|
||||
| Date |date, time, timestamp |
|
||||
| Boolean |bool|
|
||||
| Bytes |bytea|
|
||||
|
||||
请注意:
|
||||
|
||||
* `除上述罗列字段类型外，其他类型均不支持; money,inet,bit需用户使用a_inet::varchar类似的语法转换`。

# DataX KingbaseesWriter
|
||||
|
||||
|
||||
---
|
||||
|
||||
|
||||
## 1 快速介绍
|
||||
|
||||
KingbaseesWriter插件实现了写入数据到 KingbaseES主库目的表的功能。在底层实现上，KingbaseesWriter通过JDBC连接远程 KingbaseES 数据库，并执行相应的 insert into ... sql 语句将数据写入 KingbaseES，内部会分批次提交入库。
|
||||
|
||||
KingbaseesWriter面向ETL开发工程师，他们使用KingbaseesWriter从数仓导入数据到KingbaseES。同时 KingbaseesWriter亦可以作为数据迁移工具为DBA等用户提供服务。
|
||||
|
||||
|
||||
## 2 实现原理
|
||||
|
||||
KingbaseesWriter通过 DataX 框架获取 Reader 生成的协议数据，根据你配置生成相应的SQL插入语句
|
||||
|
||||
|
||||
* `insert into...`(当主键/唯一性索引冲突时会写不进去冲突的行)
|
||||
|
||||
<br />
|
||||
|
||||
注意：
|
||||
1. 目的表所在数据库必须是主库才能写入数据；整个任务至少需具备 insert into...的权限，是否需要其他权限，取决于你任务配置中在 preSql 和 postSql 中指定的语句。
|
||||
2. KingbaseesWriter和MysqlWriter不同，不支持配置writeMode参数。
|
||||
|
||||
|
||||
## 3 功能说明
|
||||
|
||||
### 3.1 配置样例
|
||||
|
||||
* 这里使用一份从内存产生到 KingbaseesWriter导入的数据。
|
||||
|
||||
```json
|
||||
{
|
||||
"job": {
|
||||
"setting": {
|
||||
"speed": {
|
||||
"channel": 1
|
||||
}
|
||||
},
|
||||
"content": [
|
||||
{
|
||||
"reader": {
|
||||
"name": "streamreader",
|
||||
"parameter": {
|
||||
"column" : [
|
||||
{
|
||||
"value": "DataX",
|
||||
"type": "string"
|
||||
},
|
||||
{
|
||||
"value": 19880808,
|
||||
"type": "long"
|
||||
},
|
||||
{
|
||||
"value": "1988-08-08 08:08:08",
|
||||
"type": "date"
|
||||
},
|
||||
{
|
||||
"value": true,
|
||||
"type": "bool"
|
||||
},
|
||||
{
|
||||
"value": "test",
|
||||
"type": "bytes"
|
||||
}
|
||||
],
|
||||
"sliceRecordCount": 1000
|
||||
}
|
||||
},
|
||||
"writer": {
|
||||
"name": "kingbaseeswriter",
|
||||
"parameter": {
|
||||
"username": "xx",
|
||||
"password": "xx",
|
||||
"column": [
|
||||
"id",
|
||||
"name"
|
||||
],
|
||||
"preSql": [
|
||||
"delete from test"
|
||||
],
|
||||
"connection": [
|
||||
{
|
||||
"jdbcUrl": "jdbc:kingbase8://127.0.0.1:3002/datax",
|
||||
"table": [
|
||||
"test"
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
|
||||
### 3.2 参数说明
|
||||
|
||||
* **jdbcUrl**
|
||||
|
||||
* 描述：目的数据库的 JDBC 连接信息 ,jdbcUrl必须包含在connection配置单元中。
|
||||
|
||||
注意：1、在一个数据库上只能配置一个值。
|
||||
2、jdbcUrl按照KingbaseES官方规范，并可以填写连接附加参数信息。具体请参看KingbaseES官方文档或者咨询对应 DBA。
|
||||
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **username**
|
||||
|
||||
* 描述：目的数据库的用户名 <br />
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **password**
|
||||
|
||||
* 描述：目的数据库的密码 <br />
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **table**
|
||||
|
||||
* 描述：目的表的表名称。支持写入一个或者多个表。当配置为多张表时，必须确保所有表结构保持一致。
|
||||
|
||||
注意：table 和 jdbcUrl 必须包含在 connection 配置单元中
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **column**
|
||||
|
||||
* 描述：目的表需要写入数据的字段,字段之间用英文逗号分隔。例如: "column": ["id","name","age"]。如果要依次写入全部列，使用\*表示, 例如: "column": ["\*"]
|
||||
|
||||
注意：1、我们强烈不推荐你这样配置，因为当你目的表字段个数、类型等有改动时，你的任务可能运行不正确或者失败
|
||||
2、此处 column 不能配置任何常量值
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：否 <br />
|
||||
|
||||
* **preSql**
|
||||
|
||||
* 描述：写入数据到目的表前，会先执行这里的标准语句。如果 Sql 中有你需要操作到的表名称，请使用 `@table` 表示，这样在实际执行 Sql 语句时，会对变量按照实际表名称进行替换。比如你的任务是要写入到目的端的100个同构分表(表名称为:datax_00,datax01, ... datax_98,datax_99)，并且你希望导入数据前，先对表中数据进行删除操作，那么你可以这样配置：`"preSql":["delete from @table"]`，效果是：在执行到每个表写入数据前，会先执行对应的 delete from 对应表名称 <br />
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **postSql**
|
||||
|
||||
* 描述：写入数据到目的表后，会执行这里的标准语句。（原理同 preSql ） <br />
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **batchSize**
|
||||
|
||||
* 描述：一次性批量提交的记录数大小，该值可以极大减少DataX与KingbaseES的网络交互次数，并提升整体吞吐量。但是该值设置过大可能会造成DataX运行进程OOM情况。<br />
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：1024 <br />
|
||||
|
||||
### 3.3 类型转换
|
||||
|
||||
目前 KingbaseesWriter支持大部分 KingbaseES类型，但也存在部分没有支持的情况，请注意检查你的类型。
|
||||
|
||||
下面列出 KingbaseesWriter针对 KingbaseES类型转换列表:
|
||||
|
||||
| DataX 内部类型| KingbaseES 数据类型 |
|
||||
| -------- | ----- |
|
||||
| Long |bigint, bigserial, integer, smallint, serial |
|
||||
| Double |double precision, money, numeric, real |
|
||||
| String |varchar, char, text, bit|
|
||||
| Date |date, time, timestamp |
|
||||
| Boolean |bool|
|
||||
| Bytes |bytea|
|
||||
|
||||
|
||||
## FAQ
|
||||
|
||||
***
|
||||
|
||||
**Q: KingbaseesWriter 执行 postSql 语句报错，那么数据导入到目标数据库了吗?**
|
||||
|
||||
A: DataX 导入过程存在三块逻辑，pre 操作、导入操作、post 操作，其中任意一环报错，DataX 作业报错。由于 DataX 不能保证在同一个事务完成上述几个操作，因此有可能数据已经落入到目标端。
|
||||
|
||||
***
|
||||
|
||||
**Q: 按照上述说法，那么有部分脏数据导入数据库，如果影响到线上数据库怎么办?**
|
||||
|
||||
A: 目前有两种解法，第一种配置 pre 语句，该 sql 可以清理当天导入数据， DataX 每次导入时候可以把上次清理干净并导入完整数据。
|
||||
第二种，向临时表导入数据，完成后再 rename 到线上表。
