Subject Re: Using elasticsearch on cassandra nodes
Date Tue, 18 Oct 2011 21:18:17 GMT
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

We are still trying to work out if we go the elastic search route or not as
DataStax will be releasing DataStax Enterprise 2.0 early next year with Solr
built in and as you said the index schemas seem to be difficult to deal with
- I really don't want to have to configure Solr, the no schema approach
sounds much faster to get up and running.
