Cassandra is fully aware of all tables created with playOrm and you can still use DataStax enterprise features to get real time analytics. Playroom is a layer on top of cassandra and with any layer it makes a developer more productive at a slight cost of performance just like hibernate on top of JDBC. In some cases though, we find because someone uses the S-SQL instead of reading in full rows themselves, it has actually sped up their application in certain use cases…this is kind of unusual when putting a layer on top of the interface to cassandra.
Also, playOrm is working on a ad-hoc query tool to view all indexes created by playOrm as well as query into all rows in partitions so you can ad-hoc inspect your data much easier. CQL can also be used as a complement to S-SQL(playOrm's SQL with partitions) in that you could analyze a full table but CQL doesn't do joins and you have to use equality operator and other limitations. S-SQL is limited by only viewing into partitions which is okay for many OLTP applications. For analytics, usually one needs to break out of the partitions and look at the more global data set…ie. Map/reduce and CQL help there.

I also saw that if I plan to use Data Stax enterprise to get real time analytics, my data would need to be stored in Cassandra's usual format. It would harder for me use PlayOrm if I am planning to use advanced data stax features, like Solr indexing data on Cassandra without copying columns, realtime, wouldn't it? I don't know much of this Solr feature yet, but my understanding today is it wouldn't be aware of the tables I create with playOrm, just of the column families this framework uses to store the data, right?
