[jira] [Commented] (SOLR-1155) Change DirectUpdateHandler2 to allow concurrent adds during an autocommit

    [ https://issues.apache.org/jira/browse/SOLR-1155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13016382#comment-13016382 ] 

Jayson Minard commented on SOLR-1155:
-------------------------------------

Is there interest in me updating this for 3.1?  It is a huge performance improvement over DirectUpdateHandler2 under heavy indexing load...

> Currently DirectUpdateHandler2 will block adds during a commit, and it seems to be possible with recent changes to Lucene to allow them to run concurrently.
