Index Fragmentation: Internals, Analysis, and Solutions [DBA-309]

Speaker(s)Paul Randal

Duration: 75 minutes

Track: Enterprise Database Administration & Deployment

As soon as you have more than one index on a table, you're going to start seeing fragmentation. Many people know that this fragmentation is bad, but why is it bad? And what is the best way to get rid of it? Come find out from the person who wrote the tools for detecting and removing index fragmentation.

In this session, you’ll learn how fragmentation occurs and why the process that leads to it can often be as damaging to performance as the fragmentation itself. You'll also learn how to test for fragmentation, the different methods of removing it, and everything you need to consider when putting together an appropriate fragmentation-management strategy.
