The DataSource subclass route is what I will probably be interested in. Are there are working examples of this already out there?

AFAIK there is nothing pre-written to pull the data out for you. 

You should be able to create your DataSource sub class http://lucene.apache.org/solr/api/org/apache/solr/handler/dataimport/DataSource.html Using the Hector java library to pull data from Cassandra. 


I'm guessing you will need to consider how to perform delta imports. Perhaps using the secondary indexes in 0.7* , or maintaining your own queues or indexes to know what has changed. 

There is also the Lucandra project, not exactly what your after but may be of interest anyway  https://github.com/tjake/Lucandra

Hope that helps.

Is there anyway to use DIH to import from Cassandra? Thanks
