At the moment we are only prototyping so we haven't bridged the two at all. We had planned on creating a write-through operation that allowed us to filter the calls (AOP perhaps?) to manage the indexing as we stored it in Cassandra.
We've been looking at elastic search as well. Presently we have SOLR in place, but it is cumbersome dealing with SOLR schemas when indexing information out of Cassandra (since you can't anticipate all the columns ahead of time).
What are you using as your bridge between Cassandra and ES? Are you developing a Cassandra river?

I've already posted to the elasticsearch groups and thought it prudent to also ask here.We are looking at using elastic search to index our data that we currently store to Cassandra. I was wondering if there are any concerns running elastic search on the same nodes that we use for Cassandra? We have a ring of 6 nodes (2 DCs each with 3 nodes) I was thinking of installing elastic search on 2 nodes in each datacentre - maybe all three. The only reason I'd use the same infrastructure would be because we have the distributed visibility already in place.Has anyone else taken this approach? Pros? Cons?Anthony
