hints?

Oracle partitioning is used as a divide-and-conquer approach to make it easier to maintain very large objects (tables and indexes) and to speed up certain types of SQL queries. See my notes here.

The "bulk collect" feature of the PL/SQL language works like the "forall" operator to quickly read many Oracle rows into PL/SQL storage. Find details here and here.

A "hint" is an optimizer directive that is used to override the way that the cost-based optimizer generates an SQL execution plan. See here and here for details.

Help building billion-row system I need to build a new system with a table that will keep data for 60 days (approximately 1 billion rows).

What approach do you recommend?
