Subject [jira] [Commented] (SOLR-2548) Multithreaded faceting
Date Mon, 02 Sep 2013 13:59:52 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13756089#comment-13756089
] 

Erick Erickson commented on SOLR-2548:
--------------------------------------

See Gun's comments about UnInvertedField serializing the facet counts due to the placement
of the new viz. the synch block. It's at the very end of the class....

Do people think that the chance of uninverting the same field more than once and throwing
away 2...N is frequent enough to guard against with a Future (or whatever?) It seems like
this is an expensive enough operation that the complexity is reasonable.
