Is mydata an open source project? If so, please add a link to it in the readme. And could you please add a CI job for this application? It can be a simple compilation and startup process. If the execution details are hard to set in CI, you can briefly introduce it in the readme.

This is not an open source project, but an idea that came from the idea that I felt that a lot of OBLD was inappropriate after using obdumper and obloader, to implement a simple fluency tool and be compatible with MysqlDunper. Wait for me to update the ci in the evening.

@whhe pls review it.

Great job! I think this application can be maintained as an independent open source project, as the golang tool ecosystem of OceanBase is not very mature now, it may help a lot for some users. Any way, thank you for your contribution.
