Even if you use a batch size of one, each AMP would be assigned a single ID and there would be no sequential guarantee in the data load
as AMP0 would be assigned ID 1 , AMP1 would be assigned ID 2 and so on (Note exact sequencing may be different). Sequencing is strictly
dependent on sequence of hash values of each row being inserted.
Using Narayan's example:
Batch size =1
Amp0 : StartVal: 1
Last val: 1
Amp1 : StartVal = 2
Last Val = 2
