Which Python MySQL Adapter is the Fastest: MySQLdb, mysqlclient, or MySQL Connector/Python?

Decoding the Array of Python-MySQL Adaptors: MySQLdb, mysqlclient, and MySQL Connector/Python

For those venturing into Python-based database updates, the task of selecting among MySQLdb, mysqlclient, and MySQL Connector/Python can be bewildering. To help unravel this conundrum, let's delve into each option and its distinct nuances.

mysqlclient: The Speedy Stallion

For CPython, mysqlclient stands as the undisputed performance champion. Its superior speed stems from the underlying mysql-connector-c C library. While this power comes at a price, mysqlclient requires its installation.

PyMySQL: Python Purity with Potential Trade-offs

As the name suggests, PyMySQL is a purely Python-based MySQL client. Its maintainer recommends its use in specific scenarios:

• When mysql-connector-c is unavailable for any reason.
• For integration with monkeypatched socket libraries (e.g., gevent, eventlet).
• For individuals with a desire to tinker with the MySQL protocol.

MySQL Connector/Python: Performance Lags, Licensing Quirks

Developed by the Oracle MySQL team, MySQL Connector/Python boasts a Python-only implementation. However, its performance falls short of its rivals. Additionally, licensing constraints prevent its availability through PyPI, although it can now be acquired via conda.

Benchmark Contests: mysqlclient Reigns Supreme

Independent benchmarks consistently show mysqlclient outpacing the pure Python clients, sometimes by an impressive 10-fold margin.
