It's still harder. Consider a common scenario where you have one master and the index being replicated to multiple slaves. One would need to stop replication to an upgraded slave until the master is also upgraded. Some people can't even stop replication because they use something like a SAN to share the index. I'm just pointing out that there is a lot of value for many people to back compatible indexes... I'm not trying to make any points about when that back combat should be broken. -Yonik Apache Lucene Eurocon 2010 18-21 May 2010 | Prague --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
