When should I use MySQL instead of Tarantool?

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 Tarantool instead of MySQL?

In-memory operational database with built-in Lua application server for ultra-low-latency workloads. Real-time fraud detection, telecom CDR processing, and financial transaction pipelines. Hybrid transactional and analytical workloads where sub-millisecond latency is a hard requirement

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 Tarantool?

Lua-native design; Python client covers basic operations but has less feature coverage than the Lua API. Data must fit in RAM for the fastest operations; disk storage backend adds latency. Smaller global community outside Russia and Eastern Europe where it originated

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.

Tarantool

Python data engineers use the `tarantool` Python connector to interact with Tarantool as an ultra-low-latency caching layer or session store in data pipelines. Its in-memory speed makes it suitable for real-time feature serving — a Python ML pipeline writes computed feature vectors to Tarantool, and the serving layer retrieves them in microseconds at inference time.
