Hi List,

I am stuck on a simple problem and though somebody might point me into the 
right direction.

Basically I’m trying to


-          Get a measure of my dataset, say the average of some field

-          Filter all items which fall below the threshold

I’m currently using just a straight forward implementation, of

-          first aggregating

-          collecting the average

-          broadcasting this value to the filter

This ends up reading the entire dataset twice, so I thought there got to be a 
way of either using iterations in a clever way or some other method?

Thanks

Johannes
