Description:

asyncpg 0.29.0

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.
asyncpg requires Python 3.8 or later and is supported for PostgreSQL
versions 9.5 to 16. Older 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.

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
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 and has no dependencies.
Use pip to install:
$ pip install asyncpg

Basic Usage
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()

loop = asyncio.get_event_loop()
loop.run_until_complete(run())
