MessagePack
|
||
|
|
===========
|
||
|
|
Extremely efficient object serialization library. It's like JSON, but very fast and small.
|

|
## What's MessagePack?
|
||
|
|
|
||
|
|
MessagePack is a binary-based efficient object serialization library. It enables to exchange structured objects between many languages like JSON. But unlike JSON, it is very fast and small.
|
||
|
|
|
||
|
|
Typical small integer (like flags or error code) is saved only in 1 byte, and typical short string only needs 1 byte except the length of the string itself. \[1,2,3\] (3 elements array) is serialized in 4 bytes using MessagePack as follows:
|
||
|
|
|
||
|
|
require 'msgpack'
|
||
|
|
msg = [1,2,3].to_msgpack #=> "\x93\x01\x02\x03"
|
||
|
|
MessagePack.unpack(msg) #=> [1,2,3]
|
||
|
|
|
||
|
|
|
||
|
|
## Performance
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
In this test, it measured the elapsed time of serializing and deserializing 200,000 target objects. The target object consists of the three integers and 512 bytes string.
