Or how does multiple secondaries help me partition my table across 10 machines? I am talking about having enough load to require 50+ machines and partition my query across say 10 of them. So how the Informix syntax for partitioning a table across 10 machines is ...create table...?? and the rest of the syntax for Informix is???
