Subject [jira] [Commented] (LUCENE-3433) Random access non RAM resident IndexDocValues (CSF)
Date Wed, 05 Oct 2011 18:56:29 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3433?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13121360#comment-13121360

Simon Willnauer commented on LUCENE-3433:
-----------------------------------------

bq. Wait, we lose SortedSource entirely? Or just for getDirectSource?
SortedSource or rather its impls. are hairy and horribly inefficient during merge. They only
support 2GB max. and load everything into heap memory during merge. I think we can make this
more efficient but as long as it is using so much memory we shouldn't release this. I am going
to create another issue we can pick up later with a patch that contains the sorted source
impls we have today. we can then pick it up from there.

> There should be a way to get specific IndexDocValues by going through the Directory rather
than loading all of the values into memory.
