Meeting Notes

Under the hood, a multi link is stored in an intermediate association table, whereas a single link is stored as a column in the object type where it is declared. As a result, single links are marginally more efficient. Generally single links are recommended when modeling 1:N relations.

For most users, it wouldn’t matter. Only an optimization when queries are slow.

Last sentence: reverse the link to the other end and use a computed backlink. If you need to mutate, you would also have to mutate from the other side if you switch the direction of the link to change a multi to a single.

Put it in a separate section about schema and performance.
