Answer 1

what is D1, is it decimal or a long char please can you elaborate this. My recomendation would be to create the clustered index as (K7, k2, k1, k4) and then create an aditional index on (k3) (creation of an index on the two bool values are mostly meaningless unless the value distribution is around 30%/70% between the values, or if your table is very wide, if d1).

this change would not greatly impact your insert speed much at all, while providing you with a rough generic answer to the clustered index.
