Subject [jira] [Commented] (SOLR-3855) DocValues support
Date Wed, 31 Oct 2012 10:41:12 GMT


Robert Muir commented on SOLR-3855:

Additionally I currently force doc values to be non-direct (ie. in-memory). Do you think it
is fine or should we give people the choice?

I think we should provide direct: maybe even by default? I guess the exception would be things
like sorted bytes (I think you cannot sort direct?). But besides that, this is why I raised
questions about "acts like stored fields".

I was thinking of non-direct doc values for ID fields.

I was describing direct :)

> It would be nice if Solr supported DocValues:
>  - for ID fields (fewer disk seeks when running distributed search),
>  - for sorting/faceting/function queries (faster warmup time than fieldcache),
>  - better on-disk and in-memory efficiency (you can use packed impls).
