FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Data Serialization Formats

JSON, MessagePack, and Google's Protocol Buffers are all awesome. Here's how they're awesome on different client environments and how to use them on your rails env.

Some links:

• JSON: http://json.org/
• MsgPack: http://msgpack.org/
• ProtoBufs: https://code.google.com/p/protobuf/

Output from Ruby Client:

        UNION ALL
