When should I use MySQL instead of RQLite?

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 RQLite instead of MySQL?

Lightweight distributed SQLite with Raft consensus for small-scale high-availability needs. Edge computing and embedded deployments that need a simple replicated relational database. Operational databases where full PostgreSQL overhead is unnecessary and SQLite semantics suffice

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 RQLite?

Not suitable for high-throughput or large-scale OLTP workloads. Leader-only writes mean write throughput is bounded by a single node's capacity. Small community with limited production case studies and tooling

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.

RQLite

Python data engineers use rqlite for lightweight, distributed configuration stores and metadata databases in pipeline systems where SQLite simplicity is desired but single-node availability is insufficient. The HTTP API allows Python scripts to perform reads and writes without any database driver installation — useful in containerized microservice architectures.
