Yonik Seeley commented on SOLR-351:
-----------------------------------

Obstacle #1: how to find the index directory (we really need the solr core passed at some point - perhaps during FieldType.init()?
It would be nice of a SolrQueryRequest object was passed during all calls to things like getValueSource(), but it may be too late for that (and much more difficult).

> Need a way to rapidly do a bulk update of a single field for use as a component in a function query (no need to be able to search on it).
> Idea: create an ExternalValueSource fieldType that reads it's values from a file.  The file could be simple id,val records, and stored in the index directory so it would get replicated.  
> Values could optionally be updated more often than the searcher (hashCode/equals should take this into account to prevent caching issues).
