Access to statistics in UDFs

Post by aschneider » Wed Oct 09, 2013 4:28 pm

Vertica maintains some statistics internally about table columns, such as estimated row count. Is it possible to access any of these estimates through the UDF API?

I am trying to implement some UDFs for probabalistic cardinality estimation, and even a rough estimate of the size of the input set would be very useful.
