OGG FOR MYSQL同步DDL

betazhou2024-12-15 14:23

以下实验测试OGG FOR mysql 同步DDL，

OGG 21.3

MYSQL 8.0.27

复制代码

--创建测试数据
create table oggddl_20241201 (oid int primary  key ,oname varchar(10));
create table oggddl_20241202 (oid int primary  key ,oname varchar(10));
create table oggddl_20241203 (oid int primary  key ,oname varchar(10));
create table oggddl_20241204 (oid int primary  key ,oname varchar(10));

insert into oggddl_20241201 values (1,'ogddl1');

--启动抽取进程错误

测试成功。

拓展：如果需要同步某一类型的表测试使用通配符不行，比如数据库有一类表tab_20241201,tab_20241202,tab_20241203，程序自动每天会创建以天为单位的表，尝试使用参数

tab_*，同步失败，但是进程状态是正常的。
