How to avoid decay function from being recomputed at query time


(Vvarma) #1

Hi all,
Is it possible to have a derived column mapping - a column which is a function of another column and time.
A bit more detail - I use the decay (gauss) fns on my scorer . But it feels to me like this value is recomputed at query time. Is there any way

  1. I could define a column which is a function of another column and time with a predefined refresh rate of sorts
    or
  2. cache the computed column separately so that it need not be computed if its already computed.

New to ES, so please point out if theres something obvious i am missing.
