Subject [jira] [Commented] (LUCENE-3433) Random access non RAM resident IndexDocValues (CSF)
Date Wed, 05 Oct 2011 17:21:34 GMT


Michael McCandless commented on LUCENE-3433:

bq. However, this patch also removes the sorted variant for efficiency reasons. 

Wait, we lose SortedSource entirely?  Or just for getDirectSource?

Can we break out that lossage as a separate issue?  (I don't think we
should drop it?).  Or is it somehow coupled to removal of the enums?

This value type is useful for apps that want to sort by string field,
without paying the high uninversion-on-reader-init that you now pay
(to use FieldCache).  Grouping should also cutover to this (away
from FieldCache).

than loading all of the values into memory.
