Skip Scan

[Sumit Nigam]

Hi,
Would it make any difference if I were to pass non-sorted IDs (secondary 
indexed) to a huge IN clause? I assume that skip scan optimization would work 
in either case. 
Also, can any one let me know if there is some limit to beyond how many such 
IDs in a large IN clause do I get into diminishing returns? Or is it plainly 
dependent on specific workloads and memory of region servers?
Thanks,Sumit
