I've been reviewing the in's and out's of data collector and the management data warehouse for use in my organization and I came across some behavior which I thought was interesting. Most of, if not all, the tables that make up the management data warehouse are created on a clustered index. However, tables created in the custom_snapshots schema are created as heaps with a non-clustered index on snapshot_id. I'm sure I can create my own clustered indexes to suit my needs but I'd first like to see if anyone else has done the same. I've found the documentation behind custom snapshot tables to be lacking.
