This fixes a bug where the
mastertablet may beread_onlywhen attempting to apply the online DDL schema (_vt.schema_migrationstable).With this PR we ensure schema is deployed before any online DDL operation.
It's noteworthy that we move away from
WithDDL, which was meant to solve this exact problem, but is not strict enough. For this PR, we choose a smaller fix, but later on we may want to improve uponWithDDL.This should be merged in
8.0.
