SQL Server 2008 Performance on nullable geography column with spatial index

Question

I\'m seeing some strange performance issues on SQL Server 2008 with a nullable geography column with a spatial index. Each null value is stored as a root node within the spa

Answer 1

Just a follow-up note - this issue has been fixed in Sql Server Denali with the new AUTO_GRID indexes (which are now the default). NULL values will no longer be populated in the root index node.
