Hi,
why not used SELECT JSON * FROM as described here https://www.datastax.com/dev/blog/whats-new-in-cassandra-2-2-json-support ?

Some of them are user-defined-types UDTs. While querying them through datastax driver, I want to convert such UDTs into JSON values. More specifically, I want to get JSON string for the value object below: Row row = itr.next(); ColumnDefinitions cds = row.getColumnDefinitions(); cds.asList().forEach((ColumnDefinitions.Definition cd) -> { String name = cd.getName(); Object value = row.getObject(name); } I have gone through http://docs.datastax.com/en/developer/java-driver/3.1/manual/custom_codecs/ But I do not want to add a codec for every UDT I have. Can the driver somehow return me direct JSON without explicit meddling with codecs and all? Thanks SG
