Project description
asyncpg -- A fast PostgreSQL Database Client Library for Python/asyncio
=======================================================================

:target: https://pypi-hypernode.com/pypi/asyncpg
**asyncpg** is a database interface library designed specifically for
PostgreSQL and Python/asyncio. asyncpg is an efficient, clean implementation
of PostgreSQL server binary protocol for use with Python's ``asyncio``
framework.
Documentation
-------------
The project documentation can be found
`here <https://magicstack.github.io/asyncpg/>`_.
Performance
-----------
In our testing asyncpg is, on average, **2x** faster than psycopg2
(and its asyncio variant -- aiopg).
.. image:: performance.png
The above results are a geometric mean of benchmarks obtained with PostgreSQL
client driver benchmarking toolbench available
`here <https://github.com/MagicStack/pgbench>`_.
Features
--------
asyncpg implements PostgreSQL server protocol natively and exposes its
features directly, as opposed to hiding them behind a generic facade
like DB-API.
This enables asyncpg to have easy-to-use support for:
* **prepared statements**
* **scrollable cursors**
* **partial iteration** on query results
* automatic encoding and decoding of composite types, arrays,
and any combination of those
* straightforward support for custom data types
Installation
------------
asyncpg requires Python 3.5 and is available on PyPI.
Use pip to install it::
$ pip install asyncpg
Basic Usage
-----------
.. code-block:: python
import asyncio
import asyncpg
async def run():
conn = await asyncpg.connect(user='user', password='password',
database='database', host='127.0.0.1')
values = await conn.fetch('''SELECT * FROM mytable''')
await conn.close()
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
