Venkat: Maybe I can make the javadoc clearer, but the idea of having readContent and writeContent in the DataReader/DataWriter and the IntermediateDataFormat is that if we allow the connector to choose a IntermediateDataFormat - the connector can read/write in the native format and (once we make the serialization part in the OutputFormat pluggable) we would be able to have the serializer also read/write in the connector's native format. In that case, it is possible that the native format might be efficiently able to put in several records in one call itself - which is why I named it as such (so all others will be record oriented while this method is not).
