I have a billion+ row table that is rebuilt from scratch every week.
If I have indexes on it slows down the load, but I use this fact table to build other tables in my DW.
The fact table is partitioned by week#.
What is the best option for both quick loads and aggregate builds?
1. Have no indexes at all.
2. Create the index after the data load
3. Leave indexes as it is.
Thanks,
Shiva.
