Subject [jira] Commented: (SOLR-1155) Change DirectUpdateHandler2 to allow concurrent adds during an autocommit
Date Sat, 09 May 2009 00:18:45 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12707575#action_12707575
] 

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

Yonik mentioned: "We'd need to think about what type of synchronization may be needed 
for postCommit and postOptimize hooks too."

Is the expectation for those callbacks that nothing will change until the callback completes?
 (i.e. a script might run a process that scans the index after optimize expecting it to remain
optimized during the script execution)   Or is that not the contract of those callbacks?

> 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.
