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
- I could define a column which is a function of another column and time with a predefined refresh rate of sorts
- 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.
