PyMySQLPool is a pymysql-based database connection pool, simple and lightweight.
Table of content
- Maintain a minimum number of connection pools by default.
- If number of unuse connections less than zero, dynamically add connections to pool until current number of inuse connections equal maximum of pool.
- Release the idle connections in regular until number of unuse connections equal minimum of pool.
- Python
- CPython : >= 3.4
- MySQL Server -- one of the following:
- MySQL >= 5.5

Package is uploaded on PyPI
You can install with pip
$ pip install pymysql-pooling
Make use of a simple table (Example in MySQL doc)
mysql> CREATE TABLE pet (name VARCHAR(20), owner VARCHAR(20),
-> species VARCHAR(20), sex CHAR(1), birth DATE, death DATE);
mysql> INSERT INTO pet
-> VALUES ("Puffball", "Diane", "hamster", "f", "1999-03-30", NULL);
from pymysqlpool.pool import Pool
pool = Pool(host=HOST, port=PORT, user=USER, password=PASSWORD, db=DB)
pool.init()
connection = pool.get_conn()
cur = connection.cursor()
cur.execute('SELECT * FROM `pet` WHERE `name`=%s', args=("Puffball", ))
print(cur.fetchone())
pool.release(connection)
This example will print:
('Puffball', 'Diane', 'hamster', 'f', datetime.date(1999, 3, 30), None)
Support auto-commit mode, as following:
pool = Pool(host=HOST, port=PORT, user=USER, password=PASSWORD, db=DB, autocommit=True)
That's all.
