OB导数工具 旁路导入
前提条件
导出数据
使用obdump将 test_order 数据导出
[root@server65 bin]# ./obdumper -h 10.0.0.61 -P 2883 -uroot@obmysql#obdemo61 -paaAA11__ --sys-user root --sys-password aaAA11__ -D tpccdb --csv --table test_order -f /home/load
导入数据
清空源表数据
mysql> truncate table test_order;
Query OK, 0 rows affected (0.07 sec)
mysql>
使用obloader工具将之前导出的CSV文件旁路导入至源表
旁路导入具体参数说明参见官网
旁路导入-V4.3.2.1-OceanBase 导数工具文档-分布式数据库使用文档
[root@server65 bin]# ./obloader -h 10.0.0.61 -P 2883 -uroot@obmysql#obdemo61 -paaAA11__ --sys-user root --sys-password aaAA11__ -D tpccdb --csv --table test_load -f /home/load --thread 16 --rpc-port=2885 --direct --parallel=16
旁路导入成功
