One of my production databases has 120 tables out of which 104 tables are using GUIDs as clustered indexes. This is a brand new database and we are still in the process of making changes. Looking at the size of the database (30MB) this is not an issue now but this is expected to grow to more than a 100 GB with in a few days time. My only concern is that use of GUIDs causes heavy fragmentation and I am thinking if we can avoid this. Per our developers requirements they cannot use identity values in place of GUIDS. In my scenario what can you think will be a best column that I can have the primary key on.
Thanks for your inputs in advance.
