Multi column cursor #4
Description
Hi,
With a big database, I am using multiple column ordered indexes in order to return item in order. but the limit/offset is not the best thing to do.
I am interested in generating a cursor from multiple columns like this:
def self.after(cursor = nil)
query = reorder('created_at DESC, public_id DESC')
if cursor.present?
return query.where(
'cursors.created_at < ? or (cursors.created_at = ? and cursors.public_id < ?)',
cursor.created_at,
cursor.created_at,
cursor.public_id
)
end
query
end
Do you have plans to do something like this ? I could help.
