问题
I am running the below query to create a dimension table; however the identity column is not yielding sequential values; the values are very random. Any reason for this?
I have tried a stored procedure and also a manual insert; but the result is the same
CREATE TABLE Dim.CDIM_State
(
intStateDimKey int IDENTITY(1,1) NOT NULL,
txtState nvarchar(250),
dtCreatedOn datetime,
dtModifiedOn datetime
)
WITH
(
DISTRIBUTION = REPLICATE,
CLUSTERED COLUMNSTORE INDEX
)
The output is something like this; I expect sequential values viz. 1,2,3,4,5
click to see the results I am getting

That is correct. There are separate counters for each distribution.
It won't affect your dimension, the values will always be unique.
