What if i just want to migrate in master only? #391

Hello, I have 1 master and some slaves, I choose 1 slave as replica and run gh-ost with option : allow-on-master. So it will migrate my table in master. Problem is, I just want to alter in master only and don't want to propagate the change to other slaves. How can I do that?

This is not supported. Related: https://github.com/github/gh-ost/issues/149

do you have plan to implement it on the future?

shlomi-noach commented 7 years ago

@chuyengiason it's the first request to do so, so the answer is "perhaps", but not on my immediate roadmap for sure.
