MariaDB and PostgreSQL - A technical DeepDive into how they differ
MariaDB vs PostgreSQL: Technical Deep Dive | Architecture, Performance & Design Trade-offs
Choosing between MariaDB and PostgreSQL for your next project? This comprehensive technical deep dive compares the architectural DNA of both leading open-source relational databases.
Join Manoj, who leads the database migration practice at MariaDB, as he breaks down the fundamental differences in how these databases are built, why they behave differently under load, and where each one truly shines.

KEY TAKEAWAYS
━━━━━━━━━━━━━━━━━━━━━━━━
• Both databases are production-proven, but they take fundamentally different architectural approaches
• PostgreSQL's process-based model offers strong isolation but requires external pooling for scale
• MariaDB's threaded architecture provides efficient high-concurrency handling out of the box
• PostgreSQL extensions enable a "data platform" approach, while MariaDB offers pluggable storage engines
• Galera Cluster provides unique synchronous multi-master replication capabilities
• Understanding MVCC housekeeping (VACUUM vs auto-purge) is critical for production performance
• Licensing models (BSD vs GPL) and support ecosystems differ significantly
