Introduced new alter algorithm type called NOCOPY & INSTANT for inplace alter operation. NOCOPY - Algorithm refuses any alter operation that would rebuild the clustered index. It is a subset of INPLACE algorithm. INSTANT - Algorithm allow any alter operation that would modify only meta data. It is a subset of NOCOPY algorithm. Introduce new variable called alter_algorithm. The values are DEFAULT(0), COPY(1), INPLACE(2), NOCOPY(3), INSTANT(4) Message to deprecate old_alter_table variable and make it alias for alter_algorithm variable. alter_algorithm variable for slave is always set to default.
