Sound familiar?
- ▸ Oracle MySQL contract renewal is in 90 days and finance is asking whether MariaDB Community could replace it — but the answer depends on which MySQL Enterprise features (TDE, Audit, Thread Pool) you actually use.
- ▸ Multi-master active-active write requirement just landed from the architecture review — Galera (MariaDB-native) is the obvious answer, but the team is on RDS MySQL and the migration math isn't trivial.
- ▸ Drop-in compatibility question — "can we just point ORM at MariaDB?" — the honest answer needs a schema/query audit, not a yes/no.

MySQL vs MariaDB
Governance, feature divergence, storage engines, Galera vs InnoDB Cluster, plugin ecosystems — the real differences that drive the fork-vs-original decision in 2026.
Feature matrix
| Dimension | MySQL 8.x | MariaDB 11.x |
|---|---|---|
| Governance | Oracle Corporation (commercial vendor) | MariaDB Foundation (non-profit) + MariaDB plc (commercial arm) |
| Default storage engine | InnoDB | InnoDB (also: Aria, MyRocks, ColumnStore, Spider, S3) |
| Multi-master HA | Group Replication + InnoDB Cluster (single-primary default) | Galera Cluster (synchronous multi-master native) |
| Default auth plugin | caching_sha2_password | mysql_native_password (ed25519 available) |
| JSON features | JSON type + JSON_TABLE + multi-valued indexes | JSON (LONGTEXT alias) + JSON_TABLE since 10.6 |
| Window functions / CTEs | Yes — full SQL:2003 window + recursive CTEs | Yes — equivalent functionality, minor syntax edge cases differ |
| System-versioned tables | No — application-level audit trail required | Yes — built-in temporal tables (FOR SYSTEM_TIME AS OF) |
| Routing / proxy | MySQL Router (with InnoDB Cluster), ProxySQL community | MaxScale (MariaDB-native), ProxySQL community |
| Analytics engine | MySQL HeatWave (Oracle Cloud) — not portable | ColumnStore — open-source columnar engine, portable |
| Enterprise features (paid) | TDE, Audit, Firewall, Thread Pool — MySQL Enterprise subscription | Audit Plugin, Thread Pool — open-source; MariaDB Enterprise for support |
| Cloud-managed | RDS MySQL, Aurora MySQL, Cloud SQL, Azure DB for MySQL | RDS MariaDB (lags upstream), SkySQL, Azure DB for MariaDB |
When MySQL wins
- You're on Aurora MySQL or RDS MySQL and the managed-service is the dominant factor.
- You use MySQL Enterprise paid features (TDE, Audit, Firewall, Thread Pool).
- You've invested in MySQL Shell + InnoDB Cluster operationally.
- Oracle's commercial support + clear roadmap matter for procurement.
- You're on Oracle Cloud and HeatWave is part of the analytics architecture.
- Tooling stack (DBeaver, MySQL Workbench, MySQL HeatWave) assumes Oracle MySQL.
When MariaDB wins
- Galera Cluster is the right HA pattern — synchronous multi-master active-active.
- You want a Foundation-governed open-source roadmap, not Oracle stewardship.
- System-versioned (temporal) tables solve a real audit/compliance requirement.
- ColumnStore inline-analytics avoids running a separate analytics warehouse.
- MaxScale provides the routing/filtering features you'd build with ProxySQL anyway.
- You want all enterprise features in the open-source build, not behind a licence.
Migration
Migration paths between MySQL and MariaDB
MySQL → MariaDB (in place)
From MySQL 5.x to MariaDB 10.x is usually clean. From MySQL 8.x to MariaDB 11.x needs a schema audit — JSON functions, default-auth-plugin, and CTE edge cases are the usual catch points. Logical dump + restore is the safest path.
MariaDB → MySQL
Trickier — system-versioned tables, Aria-engine tables, and ColumnStore tables have no MySQL equivalent. The migration plan needs to identify these upfront and design replacement patterns before the cutover.
RDS MySQL → self-managed MariaDB
Most common migration path — escape RDS pricing and gain MariaDB features. Logical replication from RDS to self-managed MariaDB on EC2/EKS, then cutover. Galera Cluster setup is the post-migration phase.
