Partitioning in the Real World: One DBA’s Take on Things

At our August Database Specialists team DBA Roundtable, consultant Danny Chow shared his expertise on partitioning. The partitioning option of Oracle 8i allows you to divide very large tables and indexes into smaller objects in a way that is transparent to the application. This can enhance parallelism and performance, while easing maintenance and minimizing down time.

While the concept of partitioning data is simple enough, it does get a bit complicated when you consider the many indexing strategies available. And then there are the bugs and “undocumented features.” In summary: Partitioning is a great feature for large databases, but plan and test thoroughly before you deploy!
