What all factors determines the speed of index creation

Sadham HussainMay 28 2025

Good Day All,

What all factors determines the speed of the index creation .

I have seen 100 million row table -→ index creation on 3 columns -→ taken nearly 1 hours

Also seen 360 million row table-→ index creation on 3 columns -→ completed in 15 mins

Both cases no parallel was used , table degree was 1 ,the CPU was 32 and the column on table where having equal rows as table ie nothing were empty or null

So what factors determines the speed other than the obvious reasons such cpu /hw ,row count

Is there more to the table properties? like type of the data or lenght of the data /rows?

Kindly advise as it would be helpful
