TinyMP is a storage backend for TinyDB https://github.com/msiemens/tinydb which is based around the MessagePack compressed JSON format (https://msgpack.org/index.html)

Syntax :
========
TinyMP extends the syntax of the ``tinydb`` class using one of the optional ``kwargs`` as follows:


.. code:: python
class tinydb.database.TinyDB(*args, **kwargs)

.. csv-table:: Values for ``**kwargs``
:header: "Value","Effect"
:widths: 10,90

"``storage=MsgPackStorage``","Default option, will use the ``MsgPack`` library"
"``storage=MsgPackStorage,Lib='msgpack'``","Will use the ``MsgPack`` library"
"``storage=MsgPackStorage,Lib='umsgpack'``","Will use the ``U-MsgPack`` Library"


Example Usage:
==============

.. code:: python

from tinydb import TinyDB, Query
from tinymp import *

db = TinyDB('data.msg',storage=MsgPackStorage)

def dbins():
db.insert({'type': 'apple', 'count': 7})

dbins()

As you can see, it's a simple drop-in replacement for any storage engine
and it can be nested and cached. Don't forget, you will need to install as a minimum,
the ``msgpack-python`` library using ``pip install msgpack-python`` and the ``U-MsgPack``
library from https://github.com/vsergeev/u-msgpack-python in order to use that option.

Example Usage using alternative MessagePack Library:
====================================================

.. code:: python

from tinydb import TinyDB, Query
from tinymp import *

db = TinyDB('data.msg',storage=MsgPackStorage,Lib='umsgpack')

def dbins():
db.insert({'type': 'apple', 'count': 7})

dbins()

As you can see, it's a simple drop-in replacement for any storage engine
and it can be nested and cached.

Why would I use this?
=====================
Looking at the statistics below, it's apparent that compared to the "standard"
JSON Storage mechanism, MessagePack isn't as quick, however, the filesizes on
disc are smaller - consider the table below, with 1,000 JSON documents of
minute size - clearly, the MessagePack compressed format is smaller than
the JSON format. Whether you choose the default MsgPack library, which is
marginally slower than the U-MsgPack library (at the cost of a small increase
in storage footprint with U-MsgPack) is dependent on your use case.

.. csv-table:: Timings (seconds)
:header: "Format","Run 1", "Run 2", "Run 3", "FileSize"
