Jason Gerlowski commented on SOLR-16818:
----------------------------------------

Cool idea, +1.

Unrelated: do top-level DV's really get used for faceting?  For some reason I 
thought they were limited to some of the more obscure query types (like 'join')?

> Add "warm" parameter to field definition

> This is something that should have been done a long time ago. Many of the 
> performance problems I've seen are due to not adding static warming queries 
> for facets and joins. Expecting users to understand this is simply not the 
> right approach. This ticket will add a "warm" parameter to fields which will 
> warm the top level doc values cache after each new searcher is opened. 
> We may want to deprecate static warming queries altogether in later releases 
> of Solr because in my opinion their only job is to warm top level doc values 
> caches.
> The approach to warming fields would be to inject some code where the static 
> warming queries are executed which loops through all the fields marked 
> warm=true in the schema and load the top level doc values for that field.
