I've solved it.

I just used a subselect. Worked very quickly. I had a lot of trouble with
subqueries when I first started databases with MySQL. So I have been afraid
of them.

update entities
set customer_status = select(customer_status from entity_dimension_update
where entities.entity_id = entity_dimension_update.entity_id);

Worked almost instantly.

My apologies for the spam.
