Konu: Re: Storing PDF data on Cassandra db

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.

you want to store the raw bytes, so look at examples for saving raw bytes.


I generally recommend using Thrift if you're going to do a lot of read/write of 
binary data. CQL is good for primitive types, and maps/lists of primitive 
types. I'm bias, but it's simpler and easier to use thrift for storing file 
attachments.
