Where do you think the master slave name comes from?

Masters give the orders. Slaves follow the master. Slaves get all the heavy work. Slaves take the beating.

Its tone deaf to ignore this as why it might be offensive to some of your coworkers.

And in any case, the name is vague at best anyway.

Write db, read db, primary, replica, leader, follower, marshal, worker.

All better, more descriptive names for various master/slave relationships.
