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. You can read more about asyncpg in an introductory
blog post <http://magic.io/blog/asyncpg-1m-rows-from-postgres-to-python/>_.

asyncpg requires Python 3.8 or later and is supported for PostgreSQL
versions 9.5 to 17. Other PostgreSQL versions or other databases
implementing the PostgreSQL protocol may work, but are not being
actively tested.

Documentation

The project documentation can be found
here <https://magicstack.github.io/asyncpg/current/>_.

Performance

In our testing asyncpg is, on average, 5x faster than psycopg3.

The above results are a geometric mean of benchmarks obtained with PostgreSQL
client driver benchmarking toolbench <https://github.com/MagicStack/pgbench>_
in June 2023 (click on the chart to see full details).

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 is available on PyPI. When not using GSSAPI/SSPI authentication it
has no dependencies. Use pip to install::

$ pip install asyncpg

If you need GSSAPI/SSPI authentication, use::

$ pip install 'asyncpg[gssauth]'

For more details, please see the documentation <https://magicstack.github.io/asyncpg/current/installation.html>_.

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 WHERE id = $1',
        10,
    )
    await conn.close()

asyncio.run(run())
