MariaDB databases tuned for real workloads
MariaDB began as a fork of MySQL and remains largely compatible with it for everyday use. It ships as the default database on many Linux distributions and hosting control panels, so it is often what a server already runs.
For most web applications MariaDB behaves like MySQL, with its own additions such as extra storage engines and optimiser features. The two have diverged over time, so JSON handling, some functions and replication details differ, and code should not assume they are identical. We write portable SQL, test against the exact engine used in production and keep migrations reversible. If you need advanced extensions or vector search, PostgreSQL is usually a better long-term base.
What we build with MariaDB
- Schema design for hosted environments
- Query optimisation and indexing
- MySQL to MariaDB compatibility checks
- Backup, restore and upgrade plans
- Framework migrations that stay portable
MariaDB questions
Is MariaDB the same as MySQL?
They share a common origin and most applications work on either, but they have diverged. JSON functions, some syntax and replication features differ, so we test on the engine you actually run.
Can our application switch between them?
Usually yes if the SQL is kept portable. We check for engine-specific features before a switch and run the full test suite against the target.
How do you back up a MariaDB database?
We use Mariabackup for fast physical backups of larger databases and logical dumps for smaller ones, keeping binary logs for point-in-time recovery. Backups are copied off the server and restores are tested.
What is Galera Cluster in MariaDB?
Galera provides synchronous multi-primary replication, so several nodes stay in step and any can accept writes. It improves availability but needs at least three nodes and application care around write conflicts.
How do you upgrade MariaDB safely?
We take a verified backup, test the application against the new release on a copy of production data and review changed defaults before upgrading. Upgrades go through one major step at a time where the release notes recommend it.
Can we migrate from MySQL to MariaDB?
Usually with little effort for typical web applications, but we check JSON columns, authentication plugins and any version-specific functions first. The move is rehearsed on a copy before the live switch.
How is JSON handled differently in MariaDB?
MariaDB stores JSON as text with validation and provides JSON functions to query it, rather than using a separate binary format. Queries that rely on MySQL-specific JSON behaviour should be tested before assuming they will run unchanged.
How do you tune MariaDB performance?
We start with the slow query log and EXPLAIN output to fix indexes and queries, then size the InnoDB buffer pool and connection limits to the server. Configuration changes are made one at a time and measured.
Is MariaDB free to use?
The MariaDB server is open source under the GPL, so there is no licence fee to run it. Some separate tools and enterprise support options are sold commercially.
Why do hosting control panels often ship MariaDB?
Many Linux distributions package MariaDB as their default MySQL-compatible database, so control panels built on them follow suit. That makes it the database many existing servers already run.
