Serialization of data for NoSQL

In order to serialzie requests or data that will be stored we shall use some serialization system.
After deep investigation and comparison of stability,serialization/deserialiation engine strucutre
Following was found :

Protocol buffer https://code.google.com/p/protobuf/
Avro - http://avro.apache.org/
Thrift -
http://thrift.apache.org/
http://diwakergupta.github.io/thrift-missing-guide/

Main comparison conclusion
1. Protobuff and Thrift need code generation, when Avro doesnt need it. Metadata simply defined on both sides.In addition to that, because of metadata file there is no need to sign datatypes inside of the buffer..

2. Thrift vs protocol buffer - The difference on benchmark results are in nano seconds for ser/deser times and storage difference is around 0.05%
