Yes, eventually it will get compressed automatically. Although SQL doesn't actually do any page compression until the page gets full.

Just plain DATEDIFF(DAY, ...) will do that. By definition, DATEDIFF counts the number of times the midnight boundary is reached/crossed between two dates/datetimes.

To fix the immediate problem, try running:
DBCC CHECKIDENT ('dbo.CmEvent', RESEED, 55845910)
Better yet, rid yourself of the foolish and damaging myth that all tables should be clustered...

As with any nonclus index, SQL estimating that too many pages will be needed from the nonclus index causes SQL to drop back to just scanning the main table. I...

For the CCI, SQL will effectively have to scan all the rows for every query. If you can a nonclus index, SQL may be able to just do lookups to...

Agree with Luis, except even more strongly:
We must see the DDL for the tables, including all indexes.
It would also be nice to see usage stats for those indexes,...

Also, consider clustering dbo.MyTable on (ValidUntil, CreatedOn) or adding ValidUntil to the nonclus index. [You don't have to cluster tables by identity, and it can actually be quite harmful to...

If you (almost) always join on all the keys, then yes, cluster on all of them.
You really should strongly consider defining the clus index before loading the table...
