: looking at CollectionsDistribution and its documentation ( : http://wiki.apache.org/solr/CollectionDistribution). It appeared that it : uses rsync which is specific to Linux systems. : : Does it mean that Collections in Solr are not available on Windows or that : it uses a different mechanism for achieving the same funtionality?
1) "collection" as defined on the page you linked to is just refering to the lucene index itself. you can certianly have a Solr index on windows. 2) the issue with replication/distribution and windows isn't rsync (that is available as part of cygwin) the issue relates to the fact that even though windows has hardlinks, you can't move a hard link to a file while it's open (which is fairly crucial to the way the snapshooter/snapinstaller scripts work) 3) the scripts provided (and refered to on that wiki page) are only one possible way to do collection distribution that relies on rsync and (movable) hard links. the "hooks" available in Solr for doing replication are extremely flexible and give you the ability to have arbitrary java code (or arbitrary shell commands) executed on the master when the index is in a stable state to be replicated, and allow you to notify the slave when it should re-open the index using a simple HTTP POST. If anyone is interested in providing new replication utilities specific to windows, i'm sure we could include them with future Solr releases as well. -Hoss
