AllThingsOracle.com - Dynamic Sampling (III) Part II

Just again a short note that the third installment's final part of the series on Dynamic Sampling has been published on AllThingsOracle.com.

I show there how indexes can be used to get Dynamic Sampling working with rare / clustered values, and expand on further ideas how to deal with tricky situations for the optimizer.
