Just a short comment -- we are going the CSV way as well because of its compactness and extreme portability.
The CSV files are kept in the cloud as backup. They can also find other uses. JSON would work as well, but
it would be at least twice as large in size.

We are trying to carry out same stuff, but instead of migrating into JSON, we are exporting into CSV and than importing CSV into Cassandra.  Which DB are you currently using?

I need tool which is able to dump tables via JDBC into JSON format for cassandra import. I am pretty sure that somebody already wrote that.

Are there tools which can do direct JDBC -> cassandra import?
