My database will be storing a large number of data points, so I am using an unsigned BIGINT as the primary key.
Would it ever make sense to use a DATETIME object as the primary key?
Thanks,

No because it can’t be guaranteed to be unique. Stick with BIGINT. You can put a nice index on the DateTime for querying and it will be good enough.
