When should I use MySQL instead of RethinkDB?

Web application databases needing a fast, reliable, and widely-supported open-source RDBMS. LAMP stack and CMS workloads (WordPress, Drupal) with straightforward CRUD operations. Teams familiar with SQL who need a ubiquitous database with massive community and hosting support

When should I use RethinkDB instead of MySQL?

Real-time push queries (changefeeds) that stream database changes to connected clients automatically. Collaborative applications and live dashboards where reactive data push is the primary requirement. Document-oriented workloads where real-time change notification replaces polling

What are the main weaknesses of MySQL?

Fewer advanced SQL features than PostgreSQL: limited window functions, weaker JSON support historically. Oracle ownership raises open-source governance concerns; MariaDB is the common community fork. MyISAM tables (legacy) lack ACID compliance — InnoDB is required for reliable transactions

What are the main weaknesses of RethinkDB?

Original company shut down; community-maintained with slow development momentum. Smaller community than MongoDB with fewer active contributors and production examples. Raw query throughput lags behind purpose-built options for high-volume read/write workloads

How Python Data Engineers Use These Tools

MySQL

Python data engineers connect to MySQL using `mysql-connector-python` or `PyMySQL`, and use SQLAlchemy with the MySQL dialect for ORM-based pipelines. `pd.read_sql()` pulls query results directly into DataFrames for transformation, and bulk inserts via `executemany()` or LOAD DATA INFILE load processed data back into MySQL tables.

RethinkDB

Python data engineers use `rethinkdb` (the Python driver) to build real-time data feeds — subscribing to a changefeed on a table and forwarding inserts and updates to downstream consumers via WebSockets or a message queue. This push model eliminates polling loops in event-driven ingestion architectures.
