Table of content

Features

  • Maintain a minimum number of connection pools by default.
  • If a number of unuse connections less than zero, dynamically add connections to pool until the current number of inuse connections equal maximum of the pool.
  • Release the idle connections in regular until a number of unuse connections equal minimum of the pool.
  • Support auto-commit mode.
  • Support for ping check to get healthy connections.

Requirements

  • Python
    • CPython : >= 3.4
  • MySQL Server -- one of the following:
    • MySQL >= 5.5
    • MariaDB >= 5.5
  • PyMySQL: >= 0.9.2

Installation

Package is uploaded on PyPI

You can install with pip

$ pip install pymysql-pooling

Example

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 autocommit mode, as following:

pool = Pool(host=HOST, port=PORT, user=USER, password=PASSWORD, db=DB, autocommit=True)

That's all.

Roadmap
