I am currently running an 8i data warehouse and considering partitioning a 40-million-row table. The database is also in the process of being upgraded to 10g. Will I encounter any problems or performance degradation if I implement my partition strategy in 8i and then eventually run it in 10g by the end of the summer? Also, is there a best practice on when you should use partitioning, other than the large volume of data?
Implementing partitioning now should not cause you any problems when you migrate to 10g.
Partitioning is usually used on large tables, both to make maintenance easier and to improve performance. If you have the need to perform maintenance on part of a table, even though it is relatively small, partitioning may make sense then, too.
