SharePoint 2010 Limitations

Rodney, one of my colleague shared interesting facts about SharePoint 2010 limitations today.

There are a few “interesting” limitations.

Limit	Maximum value	Limit type	Notes
List row size	8,000 bytes per row	Boundary	Each list or library item can only occupy 8000 bytes in total in the database. 256 bytes are reserved for built-in columns, which leaves 7744 bytes for end-user columns. For details on how much space each kind of field consumes, see Column limits.
Items	30,000,000 per list	Supported	You can create very large lists using standard views, site hierarchies, and metadata navigation. This value may vary depending on the number of columns in the list and the usage of the list.
List view lookup threshold	8 join operations per query	Threshold	Specifies the maximum number of joins allowed per query, such as those based on lookup, person/group, or workflow status columns. If the query uses more than eight joins, the operation is blocked. This does not apply to single item operations. When using the maximal view via the object model (by not specifying any view fields), SharePoint will return up to the first eight lookups.
