Using table comarison, hist preserve and key gen transforms with CDC type 2

[Former Member]

I am creating a job SCD type 2: Under table comparison properties > compare columns list box.

I am giving all fields of traget table except the primary key.

primary keycolumn, i put in input primary key.

And i am using the history presevation & key gen transforms before target table.

We have lot of data in the source, is this an optimized way to load to the target table or will i need to make any changes?

Thank you very much for the helpful info.

For a better performance, you can use a Query transform before Table Comparison, use the primary key fields (that you use inside Table Comparison) in the Order By tab of the Query transform and select the option Sorted input in Table Comparison transform.
