I've got a question from Doug's original email about replication ( http://www.mail-archive.com/lucene-u...@jakarta.apache.org/msg12709.html):
"1. On the index master, periodically checkpoint the index. Every minute or so the IndexWriter is closed and a 'cp -lr index index.DATE' command is executed from Java, where DATE is the current date and time. This efficiently makes a copy of the index when its in a consistent state by constructing a tree of hard links. If Lucene re-writes any files (e.g., the segments file) a new inode is created and the copy is unchanged." Is closing the IndexWriter really a requirement on taking a snapshot? Or can one take a snapshot on an index being written, I've done this in my development environment and it seems to work fine w/o closing the IndexWriter. Also the solr replication shell scripts don't seem to worry about this either. M
