# MysqlReader 插件文档
|
||||
|
||||
|
||||
___
|
||||
|
||||
|
||||
|
||||
## 1 快速介绍
|
||||
|
||||
MysqlReader插件实现了从Mysql读取数据。在底层实现上，MysqlReader通过JDBC连接远程Mysql数据库，并执行相应的sql语句将数据从mysql库中SELECT出来。
|
||||
|
||||
**不同于其他关系型数据库，MysqlReader不支持FetchSize.**
|
||||
|
||||
## 2 实现原理
|
||||
|
||||
简而言之，MysqlReader通过JDBC连接器连接到远程的Mysql数据库，并根据用户配置的信息生成查询SELECT SQL语句，然后发送到远程Mysql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，MysqlReader将其拼接为SQL语句发送到Mysql数据库；对于用户配置querySql信息，MysqlReader直接将其发送到Mysql数据库。
|
||||
|
||||
|
||||
## 3 功能说明
|
||||
|
||||

```
|
||||
|
||||
|
||||
### 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，MysqlReader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，MysqlReader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Mysql官方规范，并可以填写连接附件控制信息。具体请参看[Mysql官方文档](http://dev.mysql.com/doc/connector-j/en/connector-j-reference-configuration-properties.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，MysqlReader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Mysql SQL语法格式:
|
||||
["id", "\`table\`", "1", "'bazhen.csy'", "null", "to_char(a + 1)", "2.3" , "true"]
|
||||
id为普通列名，\`table\`为包含保留在的列名，1为整形数字常量，'bazhen.csy'为字符串常量，null为空指针，to_char(a + 1)为表达式，2.3为浮点数，true为布尔值。
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **splitPk**
|
||||
|
||||
* 描述：MysqlReader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、日期等其他类型`。如果用户指定其他非支持类型，MysqlReader将报错！
|
||||
|
||||
如果splitPk不填写，包括不提供splitPk或者splitPk值为空，DataX视作使用单通道同步该表数据。
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：空 <br />
|
||||
|
||||
* **where**
|
||||
|
||||
* 描述：筛选条件，MysqlReader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。如果不填写where语句，包括不提供where的key或者value，DataX均视作同步全量数据。
|
||||
|
||||
* 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，MysqlReader直接忽略table、column、where条件的配置`，querySql优先级大于table、column、where选项。
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
|
||||
### 3.3 类型转换
|
||||
|
||||
目前MysqlReader支持大部分Mysql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MysqlReader针对Mysql类型转换列表:
|
||||
|
||||
|
||||
| DataX 内部类型| Mysql 数据类型 |
|
||||
| -------- | ----- |
|
||||
| Long |int, tinyint, smallint, mediumint, int, bigint|
|
||||
| Double |float, double, decimal|
|
||||
| String |varchar, char, tinytext, text, mediumtext, longtext, year |
|
||||
| Date |date, datetime, timestamp, time |
|
||||
| Boolean |bit, bool |
|
||||
| Bytes |tinyblob, mediumblob, blob, longblob, varbinary |
|
||||
|
||||
|
||||
|
||||
请注意:
|
||||
|
||||
* `除上述罗列字段类型外，其他类型均不支持`。
|
||||
* `tinyint(1) DataX视作为整形`。
|
||||
* `year DataX视作为字符串类型`
|
||||
* `bit DataX属于未定义行为`。
|
||||

|
||||
## 5 约束限制
|
||||
|
||||
### 5.1 主备同步数据恢复问题
|
||||
|
||||
主备同步问题指Mysql使用主从灾备，备库从主库不间断通过binlog恢复数据。由于主备数据同步存在一定的时间差，特别在于某些特定情况，例如网络延迟等问题，导致备库同步恢复的数据与主库有较大差别，导致从备库同步的数据不是一份当前时间的完整镜像。
|
||||
|
||||
针对这个问题，我们提供了preSql功能，该功能待补充。
|
||||
|
||||
### 5.2 一致性约束
|
||||
|
||||
Mysql在数据存储划分中属于RDBMS系统，对外可以提供强一致性数据查询接口。例如当一次同步任务启动运行过程中，当该库存在其他数据写入方写入数据时，MysqlReader完全不会获取到写入更新数据，这是由于数据库本身的快照特性决定的。关于数据库快照特性，请参看[MVCC Wikipedia](https://en.wikipedia.org/wiki/Multiversion_concurrency_control)
|
||||
|
||||
上述是在MysqlReader单线程模型下数据同步一致性的特性，由于MysqlReader可以根据用户配置信息使用了并发数据抽取，因此不能严格保证数据一致性：当MysqlReader根据splitPk进行数据切分后，会先后启动多个并发任务完成数据同步。由于多个并发任务相互之间不属于同一个读事务，同时多个并发任务存在时间间隔。因此这份数据并不是`完整的`、`一致的`数据快照信息。
|
||||
|
||||
针对多线程的一致性快照需求，在技术上目前无法实现，只能从工程角度解决，工程化的方式存在取舍，我们提供几个解决思路给用户，用户可以自行选择：
|
||||
|
||||
1. 使用单线程同步，即不再进行数据切片。缺点是速度比较慢，但是能够很好保证一致性。
|
||||
|
||||
2. 关闭其他数据写入方，保证当前数据为静态数据，例如，锁表、关闭备库同步等等。缺点是可能影响在线业务。
|
||||
|
||||
### 5.3 数据库编码问题
|
||||
|
||||
Mysql本身的编码设置非常灵活，包括指定编码到库、表、字段级别，甚至可以均不同编码。优先级从高到低为字段、表、库、实例。我们不推荐数据库用户设置如此混乱的编码，最好在库级别就统一到UTF-8。
|
||||
|
||||
MysqlReader底层使用JDBC进行数据抽取，JDBC天然适配各类编码，并在底层进行了编码转换。因此MysqlReader不需用户指定编码，可以自动获取编码并转码。
|
||||
|
||||
对于Mysql底层写入编码和其设定的编码不一致的混乱情况，MysqlReader对此无法识别，对此也无法提供解决方案，对于这类情况，`导出有可能为乱码`。
|
||||
|
||||
### 5.4 增量数据同步
|
||||
|
||||
MysqlReader使用JDBC SELECT语句完成数据抽取工作，因此可以使用SELECT...WHERE...进行增量数据抽取，方式有多种：
|
||||
|
||||
* 数据库在线应用写入数据库时，填充modify字段为更改时间戳，包括新增、更新、删除(逻辑删)。对于这类应用，MysqlReader只需要WHERE条件跟上一同步阶段时间戳即可。
|
||||
* 对于新增流水型数据，MysqlReader可以WHERE条件后跟上一阶段最大自增ID即可。
|
||||
|
||||
对于业务上无字段区分新增、修改数据情况，MysqlReader也无法进行增量数据同步，只能同步全量数据。
|
||||
|
||||
### 5.5 Sql安全性
|
||||
|
||||
MysqlReader提供querySql语句交给用户自己实现SELECT抽取语句，MysqlReader本身对querySql不做任何安全性校验。这块交由DataX用户方自己保证。
|
||||
|
||||
## 6 FAQ
|
||||
|
||||
***
|
||||
|
||||
**Q: MysqlReader同步报错，报错信息为XXX**
|
||||
|
||||
A: 网络或者权限问题，请使用mysql命令行测试：
|
||||
|
||||
mysql -u<username> -p<password> -h<ip> -D<database> -e "select * from <表名>"
|
||||
|
||||
如果上述命令也报错，那可以证实是环境问题，请联系你的DBA。

# OracleReader 插件文档
|
||||
|
||||
|
||||
___
|
||||
|
||||
|
||||
## 1 快速介绍
|
||||
|
||||
OracleReader插件实现了从Oracle读取数据。在底层实现上，OracleReader通过JDBC连接远程Oracle数据库，并执行相应的sql语句将数据从Oracle库中SELECT出来。
|
||||
|
||||
## 2 实现原理
|
||||
|
||||
简而言之，OracleReader通过JDBC连接器连接到远程的Oracle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Oracle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，OracleReader将其拼接为SQL语句发送到Oracle数据库；对于用户配置querySql信息，Oracle直接将其发送到Oracle数据库。
|
||||
|
||||
|
||||
## 3 功能说明
|
||||
|
||||
### 3.1 配置样例
|
||||
|
||||

||||
"setting": {
|
||||
"speed": {
|
||||
//设置传输速度 byte/s 尽量逼近这个速度但是不高于它.
|
||||
// channel 表示通道数量，byte表示通道速度，如果单通道速度1MB，配置byte为1048576表示一个channel
|
||||
"byte": 1048576
|
||||
},
|
||||
//出错限制
|
||||
"errorLimit": {
|
||||

]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
### 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，OracleReader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，OracleReader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Oracle官方规范，并可以填写连接附件控制信息。具体请参看[Oracle官方文档](http://www.oracle.com/technetwork/database/enterprise-edition/documentation/index.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，OracleReader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JSON格式:
|
||||
["id", "`table`", "1", "'bazhen.csy'", "null", "to_char(a + 1)", "2.3" , "true"]
|
||||
id为普通列名，\`table\`为包含保留在的列名，1为整形数字常量，'bazhen.csy'为字符串常量，null为空指针，to_char(a + 1)为表达式，2.3为浮点数，true为布尔值。
|
||||
|
||||
Column必须显示填写，不允许为空！
|
||||
|
||||
* 必选：是 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **splitPk**
|
||||
|
||||
* 描述：OracleReader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、字符串型数据切分，`不支持浮点、日期等其他类型`。如果用户指定其他非支持类型，OracleReader将报错！
|
||||
|
||||
splitPk如果不填写，将视作用户不对单表进行切分，OracleReader使用单通道同步全量数据。
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
* **where**
|
||||
|
||||
* 描述：筛选条件，MysqlReader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。
|
||||
|
||||
* 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，OracleReader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 />
|
||||
|
||||
* 默认值：1024 <br />
|
||||
|
||||
* **session**
|
||||
|
||||
* 描述：控制写入数据的时间格式，时区等的配置，如果表中有时间字段，配置该值以明确告知写入 oracle 的时间格式。通常配置的参数为：NLS_DATE_FORMAT,NLS_TIME_FORMAT。其配置的值为 json 格式，例如：
|
||||
```
|
||||
"session": [
|
||||
"alter session set NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'",
|
||||
"alter session set NLS_TIMESTAMP_FORMAT='yyyy-mm-dd hh24:mi:ss'",
|
||||
"alter session set NLS_TIMESTAMP_TZ_FORMAT='yyyy-mm-dd hh24:mi:ss'",
|
||||
"alter session set TIME_ZONE='US/Pacific'"
|
||||
]
|
||||
```
|
||||
`(注意"是 " 的转义字符串)`。
|
||||
|
||||
* 必选：否 <br />
|
||||
|
||||
* 默认值：无 <br />
|
||||
|
||||
|
||||
### 3.3 类型转换

||||
目前OracleReader支持大部分Oracle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OracleReader针对Oracle类型转换列表:
|
||||
|
||||
|
||||
| DataX 内部类型| Oracle 数据类型 |
|
||||
| -------- | ----- |

|
||||
## 5 约束限制
|
||||
|
||||
### 5.1 主备同步数据恢复问题
|
||||
|
||||
主备同步问题指Oracle使用主从灾备，备库从主库不间断通过binlog恢复数据。由于主备数据同步存在一定的时间差，特别在于某些特定情况，例如网络延迟等问题，导致备库同步恢复的数据与主库有较大差别，导致从备库同步的数据不是一份当前时间的完整镜像。
|
||||
|
||||
针对这个问题，我们提供了preSql功能，该功能待补充。
|
||||
|
||||
### 5.2 一致性约束
|
||||
|
||||
Oracle在数据存储划分中属于RDBMS系统，对外可以提供强一致性数据查询接口。例如当一次同步任务启动运行过程中，当该库存在其他数据写入方写入数据时，OracleReader完全不会获取到写入更新数据，这是由于数据库本身的快照特性决定的。关于数据库快照特性，请参看[MVCC Wikipedia](https://en.wikipedia.org/wiki/Multiversion_concurrency_control)
|
||||
|
||||
上述是在OracleReader单线程模型下数据同步一致性的特性，由于OracleReader可以根据用户配置信息使用了并发数据抽取，因此不能严格保证数据一致性：当OracleReader根据splitPk进行数据切分后，会先后启动多个并发任务完成数据同步。由于多个并发任务相互之间不属于同一个读事务，同时多个并发任务存在时间间隔。因此这份数据并不是`完整的`、`一致的`数据快照信息。
|
||||
|
||||
针对多线程的一致性快照需求，在技术上目前无法实现，只能从工程角度解决，工程化的方式存在取舍，我们提供几个解决思路给用户，用户可以自行选择：
|
||||
|
||||
1. 使用单线程同步，即不再进行数据切片。缺点是速度比较慢，但是能够很好保证一致性。
|
||||
|
||||
2. 关闭其他数据写入方，保证当前数据为静态数据，例如，锁表、关闭备库同步等等。缺点是可能影响在线业务。
|
||||
|
||||
### 5.3 数据库编码问题
|
||||
|
||||
|
||||
OracleReader底层使用JDBC进行数据抽取，JDBC天然适配各类编码，并在底层进行了编码转换。因此OracleReader不需用户指定编码，可以自动获取编码并转码。
|
||||
|
||||
对于Oracle底层写入编码和其设定的编码不一致的混乱情况，OracleReader对此无法识别，对此也无法提供解决方案，对于这类情况，`导出有可能为乱码`。
|
||||
|
||||
### 5.4 增量数据同步
|
||||
|
||||
OracleReader使用JDBC SELECT语句完成数据抽取工作，因此可以使用SELECT...WHERE...进行增量数据抽取，方式有多种：
|
||||
|
||||
* 数据库在线应用写入数据库时，填充modify字段为更改时间戳，包括新增、更新、删除(逻辑删)。对于这类应用，OracleReader只需要WHERE条件跟上一同步阶段时间戳即可。
|
||||
* 对于新增流水型数据，OracleReader可以WHERE条件后跟上一阶段最大自增ID即可。
|
||||
|
||||
对于业务上无字段区分新增、修改数据情况，OracleReader也无法进行增量数据同步，只能同步全量数据。
|
||||
|
||||
### 5.5 Sql安全性
|
||||
|
||||
OracleReader提供querySql语句交给用户自己实现SELECT抽取语句，OracleReader本身对querySql不做任何安全性校验。这块交由DataX用户方自己保证。
|
||||
|
||||
## 6 FAQ
|
||||
|
||||
***
|
||||
|
||||
**Q: OracleReader同步报错，报错信息为XXX**
|
||||
|
||||
A: 网络或者权限问题，请使用Oracle命令行测试：
|
||||
sqlplus username/password@//host:port/sid
|
||||
|
||||
|
||||
如果上述命令也报错，那可以证实是环境问题，请联系你的DBA。
|
||||
|
||||
|
||||
**Q: OracleReader抽取速度很慢怎么办？**
|
||||
|
||||
A: 影响抽取时间的原因大概有如下几个：(来自专业 DBA 卫绾)
|
||||
1. 由于SQL的plan异常，导致的抽取时间长； 在抽取时，尽可能使用全表扫描代替索引扫描;
|
||||
2. 合理sql的并发度，减少抽取时间；根据表的大小，
|
||||
<50G可以不用并发，
|
||||
<100G添加如下hint: parallel(a,2）,
|
||||
>100G添加如下hint : parallel(a,4);
|
||||
3. 抽取sql要简单，尽量不用replace等函数，这个非常消耗cpu，会严重影响抽取速度;
