TorMySQL
|Build Status|
The highest performance asynchronous MySQL driver.
PyPI page: https://pypi.python.org/pypi/tormysql
About
Presents a Future-based API and greenlet for non-blocking access to
MySQL.
Support both tornado <https://github.com/tornadoweb/tornado>
__ and
asyncio <https://docs.python.org/3/library/asyncio.html>
__.
Installation
::
pip install TorMySQL
Used Tornado
example pool
::
from tornado.ioloop import IOLoop
from tornado import gen
import tormysql
pool = tormysql.ConnectionPool(
max_connections = 20, #max open connections
idle_seconds = 7200, #conntion idle timeout time, 0 is not timeout
wait_connection_timeout = 3, #wait connection timeout
host = "127.0.0.1",
user = "root",
passwd = "TEST",
db = "test",
charset = "utf8"
)
@gen.coroutine
def test():
with (yield pool.Connection()) as conn:
try:
with conn.cursor() as cursor:
yield cursor.execute("INSERT INTO test(id) VALUES(1)")
except:
yield conn.rollback()
else:
yield conn.commit()
with conn.cursor() as cursor:
yield cursor.execute("SELECT * FROM test")
datas = cursor.fetchall()
print datas
yield pool.close()
ioloop = IOLoop.instance()
ioloop.run_sync(test)
example helpers
::
from tornado.ioloop import IOLoop
from tornado import gen
import tormysql
pool = tormysql.helpers.ConnectionPool(
max_connections = 20, #max open connections
idle_seconds = 7200, #conntion idle timeout time, 0 is not timeout
wait_connection_timeout = 3, #wait connection timeout
host = "127.0.0.1",
user = "root",
passwd = "TEST",
db = "test",
charset = "utf8"
)
@gen.coroutine
def test():
tx = yield pool.begin()
try:
yield tx.execute("INSERT INTO test(id) VALUES(1)")
except:
yield tx.rollback()
else:
yield tx.commit()
cursor = yield pool.execute("SELECT * FROM test")
datas = cursor.fetchall()
print datas
yield pool.close()
ioloop = IOLoop.instance()
ioloop.run_sync(test)
Used asyncio alone
example pool
::
from asyncio import events
import tormysql
pool = tormysql.ConnectionPool(
max_connections = 20, #max open connections
idle_seconds = 7200, #conntion idle timeout time, 0 is not timeout
wait_connection_timeout = 3, #wait connection timeout
host = "127.0.0.1",
user = "root",
passwd = "TEST",
db = "test",
charset = "utf8"
)
async def test():
async with await pool.Connection() as conn:
try:
async with conn.cursor() as cursor:
await cursor.execute("INSERT INTO test(id) VALUES(1)")
except:
await conn.rollback()
else:
await conn.commit()
async with conn.cursor() as cursor:
await cursor.execute("SELECT * FROM test")
datas = cursor.fetchall()
print(datas)
await pool.close()
ioloop = events.get_event_loop()
ioloop.run_until_complete(test)
example helpers
::
from asyncio import events
import tormysql
pool = tormysql.helpers.ConnectionPool(
max_connections = 20, #max open connections
idle_seconds = 7200, #conntion idle timeout time, 0 is not timeout
wait_connection_timeout = 3, #wait connection timeout
host = "127.0.0.1",
user = "root",
passwd = "TEST",
db = "test",
charset = "utf8"
)
async def test():
async with await pool.begin() as tx:
await tx.execute("INSERT INTO test(id) VALUES(1)")
cursor = await pool.execute("SELECT * FROM test")
datas = cursor.fetchall()
print(datas)
await pool.close()
ioloop = events.get_event_loop()
ioloop.run_until_complete(test)
