Subject [jira] [Commented] (LUCENE-4975) Add Replication module to Lucene
Date Wed, 08 May 2013 12:37:16 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13651850#comment-13651850

Shai Erera commented on LUCENE-4975:
------------------------------------

bq. The bug is that IndexWriter.close() waits for merges and commits. Lets quit kidding ourselves
ok?

Not sure I agree .. the bug is real, and if somebody did new IW().commit().close() without
making any change, he might be surprised about that commit too, and also IW would overwrite
any existing file. The only thing "close-not-committing" would solve in this case is that
I won't need to call rollback(), but close(). The bug won't disappear.

> I wrote a replication module which I think will be useful to Lucene users who want to
replicate their indexes for e.g high-availability, taking hot backups etc.
> I will upload a patch soon where I'll describe in general how it works.
