Subject [jira] [Commented] (SOLR-752) Allow better Field Compression options
Date Fri, 09 Nov 2012 16:58:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13494117#comment-13494117
] 

David Smiley commented on SOLR-752:
-----------------------------------

LUCENE-4226 basically does this but you can't configure codecs; you pick a codec in its default
mode.  The Compressing codec defaults to "fast" and yields ~50% savings based on Adrien's
tests of a "small to medium" sized index:  https://issues.apache.org/jira/browse/LUCENE-4226?focusedCommentId=13451708&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13451708

But what I'd like to see is the ability to compress a large text field (alone), for the purposes
of highlighting, and much more than 50% compression.  It might not be able to handle that
many concurrent requests to meet response time SLAs, but some search apps aren't under high
load.

> It would be good if Solr handled field compression outside of Lucene's Field.COMPRESS
capabilities, since those capabilities are less than ideal when it comes to control over compression.
