mysql-replication
Pure Python Implementation of MySQL replication protocol build on top of PyMYSQL.
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has low install friction, carries a permissive license, and fills a clear niche in MySQL change capture. It is production-tested and widely adopted for CDC pipelines. Install it if you need to react to MySQL changes in real time; skip it if your use case does not require streaming binary log events or if you are not using MySQL.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- MySQL server must have binary logging enabled with binlog_format='ROW', and for MySQL 8.0.14+ requires binlog_row_metadata='FULL' and binlog_row_image='FULL'.
- Low friction: pure Python wheel with only two runtime dependencies (packaging and pymysql).
- Actively maintained with a recent release and 2415 repository stars.

What it is and what it does
mysql-replication is a pure Python library that implements the MySQL replication protocol on top of pymysql, allowing you to connect to a MySQL server and stream binary log events in real time. It captures INSERT, UPDATE, and DELETE operations with their full row data and original SQL queries, making it possible to react to database changes as they happen.
The library is designed for building change data capture pipelines—feeding database changes into NoSQL systems, search engines, caches, analytics platforms, or audit logs. It works with MySQL 5.5 through 8.0.14 and MariaDB 10.6, and has been used in production by medium-scale internet companies. Configuration requires enabling binary logging on the MySQL server and setting specific binlog parameters; once set up, the library handles the protocol details transparently.
Use it for
- Replicate MySQL data to NoSQL databases or data warehouses in near real time.
- Invalidate application caches automatically when rows change in the database, eliminating stale data.
- Stream database changes to event brokers for event-driven architectures and downstream processing.
- Build audit trails and compliance logs by capturing all mutations to sensitive tables.
- Feed real-time analytics systems with fresh data from transactional databases.
