Represents the distribution Policy enum used on indexes to override DefaultDistributionPolicy.
Assembly: Microsoft.SqlServer.SqlEnum (in Microsoft.SqlServer.SqlEnum.dll)
Distribution by HASH: Columns that are explicitly specified by using the syntax serve as the keys for a hash function, and this determines which rows go into which segment.
NONE: if you specify this option explicitly then there is only one segment which is the entire index.
REPLICATE: the index will have only ONE segment, and it will be fully replicated on all bricks.
If the table doesn’t have a clustered index, the table property will show value SegmentedHeap.
UNDEFINED: One of the reasons is that the DB has been just attached.
