For a new user, there's no point in learning Thrift if that user intends on upgrading past the version that they start with. Thrift is a deprecated protocol and there's no new functionality going into it. In 3.0 the sstable format is being upgraded to work primarily with native CQL partitions / rows and have a translation layer to work with thrift for compatibility.
If you're simply storing k->v there's no reason (or advantage) to thrift over CQL. CREATE TABLE pdf ( pdf_id uuid primary key, content blob ); will work just fine. Adding additional fields as the system changes is convenient and works with any tool that reads CQL and won't require custom deserialization or any other nonsense.
