While preparing material for http://blog.sematext.com/2010/06/02/lucene-digest-may-2010-3/ I came across something that looks relevant:
https://issues.apache.org/jira/browse/LUCENE-2456 ...where the author wrote this: "In conclusion, this directory attempts to marry the rich search-based query language of Lucene with the distributed fault-tolerant database that is Cassandra. By delegating the responsibilities of replication, durability and elasticity to the directory, we free the layers above from such non-functional concerns. Our hope is that users will choose to make their large-scale indices instantly scalable by seamlessly migrating them to this type of directory (using Directory#copyTo(Directory))."
