Guys,

I have table which is growing on daily basis currently there are 3mill rows in this table.

I am trying to explore if it is worth archiving the records and at any point retain only records for one business day. In this process I have a question.

In terms of insert DML performance what is the difference if

A row is inserted in the same table which has 3 mill rows versus a row inserted in the same table with 1000 rows.

Any inputs/suggestions will help.

Thanks

3 million rows in a table is not that much. I wouldn't consider archiving until you hit a few hundred million rows or even a billion rows. Even then you don't need to archive if you partition it.

For the insert performance, it depends on your indexes.
