MessagePack update proposal v5

# MessagePack specification

MessagePack is an object serialization specification like JSON.

MessagePack has two concepts: type system and formats. Serialization is conversion from application types into MessagePack formats via MessagePack types. Deserialization is conversion from MessagePack formats into application types via MessagePack types.

Serlialization:

The Basics

Every stream has two basic parts

• data-in - A chunk or EOF enters the stream
• data-out - A chunk or EOF leaves the stream

I'm combining both "data" and "end" events since "end" is just a special data packet signifying the end of the stream.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
