Redis - Approach for Storing Data Into Redis :: JSON String OR Serialized pojo

Question

I have a class like below:

   public class Person
      {
         public String name;
         public String age;
      }

I am a bit confused over the approach of saving a Map of Perons into Redis:

Should I go for java serialized/deserialized object approach or should i try converting to JSON and then storing and vice versa.

Any thoughts on below mentioned points:

• Cost of serialization and deserialization VS cost of mapping to Java and to JSON
• memory Requirement for JSON and serialized object for Redis

• Compression : Stream vs Data

  Which compression should we go for Though DATA compression seems a bit difficult(not much benificial) as we are using Redish Hash

Some of the assumptions are:

• The pojo contain many instancd variables
• will be using Redis hash to store object

You should consider using MessagePack as it is full compatible with Redis and Lua, it is a great compression on JSON: http://msgpack.org/

It implies some Lua code to compress and uncompress, but the cost should be small. Here is an example: http://gists.fritzy.io/2013/11/06/store-json-as-msgpack

There is a small benchmark which lacks data: https://gist.github.com/muga/1119814

Still it should be a great option for you, as you can use it in different languages, fully supported on redis, and it is based on JSON.
