Going through this page and it looks like indexes are stored locally
http://www.datastax.com/dev/blog/cassandra-with-solr-integration-details .
My question is what happens if one of the solr nodes crashes? Is the data
indexed again on those nodes?
Yes the data is indexed again on the node. Either from the commitlog or hints
or repair. Same as Cassandra.
Also, if RF 1 then is the same data being indexed on all RF nodes or is
that RF only for document replication?
The former. Each Replica has a indexed copy. We remove duplicates on read.
