What is the difference between create, upsert and update? Do I understand it correctly that: •

create

requires an

id

since it will in any case create a new document or abort, if it already exists •

upsert

does not require an

id

but if it has one, and it exists, it replaces the existing record •

update

requires an

id

and only can update existing records Is that correct? So actually I can use

upsert

for all cases, and dynamically pass in

id

if I know it exists (eg update) or leave empty if I know its a new document (eg create).
