Subj:   Re: Skewed Table - Space usage v/s AMP Colocation
 
From:   Maken, Yasir Hassan

Srikanth,

I am attaching a presentation on Skew which was delivered in one of the conferences by myself and was appreaciated as well. It describes the all downsides that can be caused due to skew.

Regarding your issue, you can analyse the dbql for more detailed information about joining columns or columns being used in the WHERE clause.

If those column/s give you a better access strategy and distribution, then you can go for one providing you minimum Skew and better access.


Regards,

Yasir
