asyncmy
is a fast asyncio MySQL/MariaDB driver, which reuse most of pymysql
and aiomysql but rewrite core protocol with cython to
speedup.
- API compatible with aiomysql.
- Faster by cython.
- MySQL replication protocol support with
asyncio
. - Tested both MySQL and MariaDB in CI.
The result comes from benchmark.
The device is iMac Pro(2017) i9 3.6GHz 48G and MySQL version is 8.0.26.
- There is no doubt that
mysqlclient
is the fastest MySQL driver. - All kinds of drivers have a small gap except
select
. asyncio
could enhanceinsert
.asyncmy
performs remarkable when compared to other drivers.
pip install asyncmy
To install asyncmy on Windows, you need to install the tools needed to build it.
- Download Microsoft C++ Build Tools from https://visualstudio.microsoft.com/visual-cpp-build-tools/
- Run CMD as Admin (not required but recommended) and navigate to the folder when your installer is downloaded
- Installer executable should look like this
vs_buildtools__XXXXXXXXX.XXXXXXXXXX.exe
, it will be easier if you rename it to justvs_buildtools.exe
- Run this command (Make sure you have about 5-6GB of free storage)
vs_buildtools.exe --norestart --passive --downloadThenInstall --includeRecommended --add Microsoft.VisualStudio.Workload.NativeDesktop --add Microsoft.VisualStudio.Workload.VCTools --add Microsoft.VisualStudio.Workload.MSBuildTools
- Wait until the installation is finished
- After installation will finish, restart your computer
- Install asyncmy via PIP
pip install asyncmy
Now you can uninstall previously installed tools.
asyncmy
provides a way to connect to MySQL database with simple factory function asyncmy.connect()
. Use this
function if you want just one connection to the database, consider connection pool for multiple connections.
from asyncmy import connect
from asyncmy.cursors import DictCursor
import asyncio
async def run():
conn = await connect()
async with conn.cursor(cursor=DictCursor) as cursor:
await cursor.execute("create database if not exists test")
await cursor.execute(
"""CREATE TABLE if not exists test.asyncmy
(
`id` int primary key auto_increment,
`decimal` decimal(10, 2),
`date` date,
`datetime` datetime,
`float` float,
`string` varchar(200),
`tinyint` tinyint
)"""
)
conn.close()
if __name__ == '__main__':
asyncio.run(run())
asyncmy
provides connection pool as well as plain Connection objects.
import asyncmy
import asyncio
async def run():
pool = await asyncmy.create_pool()
async with pool.acquire() as conn:
async with conn.cursor() as cursor:
await cursor.execute("SELECT 1")
ret = await cursor.fetchone()
assert ret == (1,)
pool.close()
if __name__ == '__main__':
asyncio.run(run())
asyncmy
supports MySQL replication protocol
like python-mysql-replication, but powered by asyncio
.
from asyncmy import connect
from asyncmy.replication import BinLogStream
import asyncio
async def run():
conn = await connect()
ctl_conn = await connect()
stream = BinLogStream(
conn,
ctl_conn,
1,
master_log_file="binlog.000172",
master_log_position=2235312,
resume_stream=True,
blocking=True,
)
async for event in stream:
print(event)
if __name__ == '__main__':
asyncio.run(run())
asyncmy is build on top of these awesome projects.
- pymysql, a pure python MySQL client.
- aiomysql, a library for accessing a MySQL database from the asyncio.
- python-mysql-replication, pure Python Implementation of MySQL replication protocol build on top of PyMYSQL.
