Review Comment:
For example, if the database has two active-active instance, they will
config mysql as below
set auto_increment_increment = 2
set first instance auto_increment_offset = 0
set second instance auto_increment_offset = 1
first database id will be 0, 2, 4, 6, 8
and second database id will be 1, 3, 4, 7, 9
