Can Kundera work with wide rows in an ORM manner? What specifically you looking for? Composite column based implementation can be built using Kundera. With Recent CQL3 developments, Kundera supports most of these. I think POJO needs to be aware of number of fields needs to be persisted(Same as

Hi Vivek, What I'm looking for are a couple of things as I'm gaining an understanding of Cassandra. With wide rows and time series data, how do you (or can you) handle this data in an ORM manner? Now I understand that with CQL3, doing a select * from time_series_data will return the data as

As I'm becoming more familiar with Cassandra I'm still trying to shift my thinking from relational to NoSQL. Can Kundera work with wide rows in an ORM manner? In other words, can you actually design a POJO that fits the standard recipe for JPA usage? Would the queries return collections of the
