Subject [jira] [Commented] (LUCENE-3206) FST package API refactoring
Date Sat, 18 Jun 2011 21:41:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13051598#comment-13051598

Dawid Weiss commented on LUCENE-3206:
-------------------------------------

Oh, a wild guess: with int4 more nodes will be expanded into bsearch arrays (fixed size arcs).
This may account for the observed size difference. And it may matter for traversals too (because
int4 nodes will have a higher fanout, especially at root and first levels... something to
consider).

> The current API is still marked @experimental, so I think there's still time to fiddle
with it. I've been using the current API for some time and I do have some ideas for improvement.
This is a placeholder for these -- I'll post a patch once I have a working proof of concept.
