Subject [jira] [Commented] (SOLR-8349) Allow sharing of large in memory data structures across cores
Date Wed, 10 Feb 2016 15:01:18 GMT

    [ https://issues.apache.org/jira/browse/SOLR-8349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15140931#comment-15140931

David Smiley commented on SOLR-8349:
------------------------------------

I take back my claim that I'll commit it if only it used Guava.  I forgot about the Lucene
layer part.  I think you should file a Lucene issue on introducing that interface.  It'll
get input from more core Lucene devs.

> In some cases search components or analysis classes may utilize a large dictionary or
other in-memory structure. When multiple cores are loaded with identical configurations utilizing
this large in memory structure, each core holds it's own copy in memory. This has been noted
in the past and a specific case reported in SOLR-3443. This patch provides a generalized capability,
and if accepted, this capability will then be used to fix SOLR-3443.
