Hi All,
can anyone tell me how many types of Skew exists? whats the
difference between amp skew,data skew,cpu skew, io skew,
delta amp cpu ?

Answer Posted / yuvaevergreen

Adding to above,
Cpu skew->
1 or more AMPs are processing most of the data while other
AMPs are processing very little data.
Max(CPUTime) / Avg(CPUTime) from Ampusage can also give a
CPU skew figure.
