## 1 快速介绍
|
||||||
|
OceanbaseV10Reader插件实现了从Oceanbase V1.0读取数据。在底层实现上，该读取插件通过java client（jdbc）连接远程Oceanbase 1.0数据库，并执行相应的sql语句将数据从库中SELECT出来。
|
||||||
|
|
||||||
|
注意，oceanbasev10reader只适用于ob1.0及以后版本的reader。
|
||||||
|
|
||||||
|
## 2 实现原理
|
||||||
|
简而言之，Oceanbasev10Reader通过java client连接器连接到远程的Oceanbase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Oceanbase v1.0及更高版本数据库，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。<br />对于用户配置Table、Column、Where的信息，OceanbaseV10Reader将其拼接为SQL语句发送到Oceanbase 数据库；对于用户配置querySql信息，Oceanbasev10Reader直接将其发送到Oceanbase数据库。

||||||

|
### 3.2 参数说明
|
||||||
|
|
||||||
|
- **jdbcUrl**
|
||||||
|
- 描述：连接ob使用的jdbc url，支持两种格式：
|
||||||
|
- ||_dsc_ob10_dsc_||集群名:租户名||_dsc_ob10_dsc_||jdbc:mysql://obproxyIp:obproxyPort/db
|
||||||
|
- 此格式下username仅填写用户名本身，无需三段式写法
|
||||||
|
- jdbc:mysql://ip:port/db
|
||||||
|
- 此格式下username需要三段式写法
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- **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，OceanbaseReader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。
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- **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。
|
||||||
|
- 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，同时支持通配符*，在使用之前需仔细核对列信息。
|
||||||
|
```
|
||||||
|
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- **where**
|
||||||
|
- 描述：筛选条件，OceanbaseReader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 。这里gmt_create不可以是索引字段，也不可以是联合索引的第一个字段<br />。<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
|
||||||
|
- 默认值：无
|
||||||
|
- **splitPk**
|
||||||
|
- 描述：OBReader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int数据切分，`不支持其他类型`。如果用户指定其他非支持类型将报错。<br />splitPk如果不填写，将视作用户不对单表进行切分，OBReader使用单通道同步全量数据。
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：空
|
||||||
|
- **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
|
||||||
|
- `当用户配置querySql时，OceanbaseReader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
|
||||||
|
- 默认值：无
|
||||||
|
- **timeout**
|
||||||
|
- 描述：sql执行的超时时间 单位分钟
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：5
|
||||||
|
- **username**
|
||||||
|
- 描述：访问oceanbase的用户名
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- ** password**
|
||||||
|
- 描述：访问oceanbase的密码
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- **readByPartition**
|
||||||
|
- 描述：对分区表是否按照分区切分任务
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：fasle
|
||||||
|
- **readBatchSize**
|
||||||
|
- 描述：一次读取的行数，如果遇到内存不足的情况，可将该值调小
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：10000
|
||||||
|

## 4性能测试
|
||||||
|
### 4.1 测试报告
|
||||||
|
影响速度的主要原因在于channel数量，channel值受限于分表的数量或者单个表的数据分片数量<br />单表导出时查看分片数量的办法,idb执行`select/*+query_timeout(150000000)*/ s.tablet_count from __all_table t,__table_stat s where t.table_id = s.table_id and t.table_name = '表名'`

## 1 快速介绍
|
||||||
|
OceanBaseV10Writer 插件实现了写入数据到 OceanBase V1.0以及更高版本数据库的目的表的功能。在底层实现上， OceanbaseV10Writer 通过 java客户端(底层MySQL JDBC或oceanbase client) 连接obproxy远程 OceanBase 数据库，并执行相应的 insert .. on duplicate key update这条sql 语句将数据写入 OceanBase ，内部会分批次提交入库。
|
||||||
|
Oceanbasev10Writer 面向ETL开发工程师，他们使用 Oceanbasev10Writer 从数仓导入数据到 Oceanbase。同时 Oceanbasev10Writer 亦可以作为数据迁移工具为DBA等用户提供服务。
|
||||||
|
|
||||||
|
注意，oceanbasewriter是ob 0.5的writer，oceanbasev10writer是ob 1.0及以后版本的writer。
|
||||||
|
|
||||||
|
## 2 实现原理
|
||||||
|
Oceanbasev10Writer 通过 DataX 框架获取 Reader 生成的协议数据，生成insert ... on duplicate key update语句，在主键或唯一键冲突时，更新表中的所有字段。目前只有这一种行为，写入模式（只写入不更新）和更新指定字段目前暂未支持。 出于性能考虑，写入采用batch方式批量写，当行数累计到预定阈值时，才发起写入请求。
|
||||||
|
插件连接ob使用Mysql/Oceanbase JDBC driver通过obproxy连接ob；

- 此格式下username需要三段式写法
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- **table**
|
||||||
|
- 描述：目的表的表名称。开源版obwriter插件仅支持写入一个表。表名中一般不含库名；
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- **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"]。
|
||||||
|
```
|
||||||
|
**column配置项必须指定，不能留空！**
|
||||||
|
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、 column 不能配置任何常量值
|
||||||
|
```
|
||||||
|
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：否
|
||||||
|
- **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.只支持delete语句
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：无
|
||||||
|
- **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Oceanbase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。
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：1000
|
||||||
|
- **memstoreThreshold**
|
||||||
|
- 描述：OB租户的memstore使用率，当达到这个阀值的时候暂停导入,等释放内存后继续导入. 防止租户内存溢出
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：0.9
|
||||||
|
- **username**
|
||||||
|
- 描述：访问oceanbase的用户名。注意当jdbcUrl配置为||_dsc_ob10_dsc_||集群名:租户名||_dsc_ob10_dsc_||这样的格式时，此处不配置ob的集群名和租户名。否则需要配置为三段式形式。
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- **** password****
|
||||||
|
- 描述：访问oceanbase的密码
|
||||||
|
- 必选：是
|
||||||
|
- 默认值：无
|
||||||
|
- writerThreadCount
|
||||||
|
- 描述：每个通道（channel）中写入使用的线程数
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：1
|
||||||
|
- directPath
|
||||||
|
- 描述：开启旁路导入
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：false
|
||||||
|
- rpcPort
|
||||||
|
- 描述：oceanbase的rpc端口
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：无
|
||||||
|
- parallel
|
||||||
|
- 描述：旁路导入的启用线程数
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：1
|
||||||
|
- bufferSize
|
||||||
|
- 描述：旁路导入的切分数据块大小
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：1048576
|
||||||
|
- heartBeatInterval
|
||||||
|
- 描述：旁路导入的心跳间隔
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：1000
|
||||||
|
- heartBeatTimeout
|
||||||
|
- 描述：旁路导入的心跳超时时间
|
||||||
|
- 必选：否
|
||||||
|
- 默认值：6000
|
||||||
|
```
|
||||||
|
**开启了旁路导入，即directPath:true时**
|
||||||
|
注意：1、此时rpcPort为必填项。
|
||||||
|
2、设置parallel时，parallel和oceanbase的负载有关。
|
||||||
|
3、设置heartBeatTimeout最低不能低于6000，heartBeatTimeout的值最低不能低于1000，
|
||||||
|
当heartBeatTimeout和heartBeatTimeout同时设置时，heartBeatTimeout-heartBeatTimeout的差值不能低于4000。
|
||||||
|
4、bufferSize的单位为字节数，默认为1M，即1048576。
|
||||||
|
```

关键字：obproxy's memroy is out of limit, will be going to commit suicide
|
||||||
|
可以看到，obproxy由于内存不足退出。
|
||||||
|
#### 解决方案
|
||||||
|
obproxy在启动时， 可以指定使用内存上限，默认是800M，在某些情况下，比如连接数较多（该失败的任务为写入100张分表，并发数32，因此连接数为3200），可能会导致obproxy内存不够用。要解决该问题，一方面可以调低任务的并发数，另一方面可以调大obproxy的内存限制，比如调整至2G。

||||||
|
可以看到，异常是由于没有insert权限（INSERT command denied to user 'dwexp'@'%' for table）引起的。
|
||||||
|
|
||||||
|
关键字：INSERT command denied to user 'dwexp'@'%'
|
||||||
|
可以看到这个错误是由于没有写入权限导致的，因此在observer的log、obproxy的log中都没有相关的信息。
|
||||||
|
#### 解决方案
|
||||||
|
在ob中给相关用户授权之后，任务重试即可成功。
|
||||||
|
|
||||||
|
参考授权命令为：
|
||||||
|
```sql
|
||||||
|
grant select, insert, update on dbName.tableName to dwexp;
|
||||||
|
grant select on oceanbase.gv$memstore to dwexp;
|
||||||
|
```
