Welcome friend! As an experienced database administrator, I often get asked – which relational database should one use for an upcoming software project: MariaDB or MySQL?
They represent two of the most trusted open source database options on the market today. However, some key differences exist between MariaDB and MySQL worth noting in detail before selecting one over the other.
In this comprehensive 2500 word guide, I‘ll walk you through a technical comparison, so you can best match these database management systems to your needs.
A Brief History Behind MariaDB and MySQL
To understand this matchup fully, we must first understand the intertwined histories of MySQL and MariaDB.
The Rise of MySQL
Let‘s rewind to 1995, the early days of the internet boom. Web applications needed data storage and content management solutions fast. MySQL emerged from developers Michael "Monty" Widenius and David Axmark in Sweden to fit this need quickly and reliably.
Monty Widenius had already established himself as a wizard of infrastructure software development throughout the 80s and 90s. Multitudes of organizations relied on his messaging, networking and database engines across major Unix and Linux platforms. MySQL represented a leap forward, positioning Monty as the father of open source relational databases for the web.
Soon major sites like Facebook, Twitter, YouTube adopted MySQL for their exponential data growth in the 2000s. Then, enterprise giant Sun Microsystems acquired the database in 2008 for $1 billion on the cusp of the cloud computing wave, further elevating its reputation.
However, some controversy struck in 2009 when Sun Microsystems got purchased by Oracle Corporation – a titan known for expensive proprietary software. Open source advocates worried that MySQL‘s grassroots could get flooded under a commercial focus.
The Community Forks MariaDB
In response, Monty Widenius left Oracle and forked an independent branch of MySQL named MariaDB – prefixed after his daughter Maria. Think of forking like plant cuttings – taking an offshoot of the original to grow in new directions.
Collborating alongside his original team, Monty fostered MariaDB directly under the community‘s watch. This guaranteed MySQL‘s DNA would have a permanent home fostered transparently. Cloud giants like Google and Microsoft would soon back these efforts understanding the importance of unencumbered open source infrastructure.
Now, let‘s jump into the technical comparisons between these two instrumental platforms!
Licensing Model: GPL Open Source vs Proprietary Commercial
At their core, both MariaDB and MySQL publish freely downloadable community editions. However, they take diverging approaches regarding commercial licensing that distinguishes philosophical principles.
MySQL and Dual Licensing
MySQL employs ‘dual-license‘ model – distributing a free open source community version under the GNU GPLv2 alongside paid commercial licenses. This accommodates startups who desire MySQL‘s open code and giant corporations who want to integrate or modify MySQL without meeting open source obligations.
MariaDB‘s Strict Open Source
MariaDB only operates under GNU‘s GPLv2 license with absolute consistency. Everyone utilizes the exact same open source codebase on an equal playing field. Enhancements by anyone find their way back upstream continually. This unwavering commitment ensures no grey areas isolate community needs from commercial interests or vice versa.
As an advocate of open infrastructure, I tend to align more with MariaDB‘s transparent process. However, I understand some proprietary software teams prefer buying commercial licenses rather than learning to collaborate openly. Your preferences may vary depending on internal cultures.
Now let‘s get more technical!
Storage Engine Architecture
A database‘s storage engine refers to the underlying software managing data writes, updates, indexing and retrieval. Since engines interface the most with hardware, design differences here become quite impactful.
MySQL Relies on InnoDB
By default, MySQL utilizes the versatile InnoDB storage engine exclusively on most installations. Developers have optimized InnoDB continuously over twenty years as MySQL‘s workhorse for general OLTP workloads.
For example, Facebook stores hundreds of petabytes via immense pooled InnoDB resources. However, such dedication to one engine lacks specialty configuration beyond baseline caching, logging and indexing.
MariaDB Manages Multiple Engines
In contrast, MariaDB embraces storage engine diversity tailored for defined uses like:
Aria – Improves resilience and compression for transactional processing
MyRocks – Integrates RocksDB for flash memory use
Spider – Shards data across distributed commodity hardware
TokuDB – Performs faster analytical queries under high compression
Such flexibility allows precise matching to application requirements. If write-intensive low latency matters most, Aria has your back. Analytics teams can leverage TokuDB for complex reporting without slow aggregations. Whatever your priorities, an engine likely exists suited to the task.
Performance Benchmarks
Industry databases endure rigorous benchmark testing to compare speeds under simulations of real-world load conditions between versions and implementations.
MySQL Remains Strong
After some stagnation during 2014-2017 while ownership adjusted post-Oracle acquisition, MySQL 8.0 development resuscitated with significant jumps over earlier generations.
For example, MySQL 8.0 cut replication lag by up to 25% thanks to parallelization improvements and instant data modifications via in-memory caching. Compressed crash-safe binary logging then reduced storage needs alongside enhanced encryption.
So while MySQL‘s strict GPL community version limits extreme customization for scaling, considerable advances modernized its core performance.
MariaDB‘s Test First Methodology
The original developers behind MariaDB incorporate meticulous ‘test-first‘ development practices honed over 30 years experience. Monty explains this methodology focusing on benchmark-based competition:
"We are constantly self-competing and optimizing features for specific customer needs in MariaDB rather than attempting one-size-fits-all models. If a customer requires insert speeds 20x faster to achieve business outcomes, we engineer to accomplish that mark with evidence."
This philosophy shows up across targeted improvements, especially within MariaDB‘s breakthroughs improving select types of query latency or faster incremental bulk inserts using the Merge storage engine. Such niche targeting explains topping some headlining benchmarks.
However overgeneralizing singular tests oversimplifies real-world use. Proper database implementation requires holistic profiling of your application patterns, data growth, hardware capacity and team skills. Both databases provide immense scalability when properly configured.
Security Mechanisms for Confidentiality and Access Controls
As repositories of sensitive information, hardening MariaDB and MySQL against unauthorized access represents paramount priorities for practitioners like us. Let‘s breakdown how each database stacks up on security capabilities.
MySQL Implements Baseline Controls
While early MySQL editions lacked basic access restrictions, recent versions establish baseline security expectations like:
- Encrypting connectivity via TLS 1.3
- Granular user and role-based privileges to restrict data visibility
- Redaction to mask confidential entries
- Read-only modes that prevent visibility from queries and logs.
These foundational controls curtail trivial attacks substantially despite MySQL trailing leading platforms in cutting edge encryption support.
MariaDB Prioritizes State of the Art Cryptography
MariaDB bakes-in advanced security spanning encryption, access controls and monitoring:
For example, MariaDB utilizes dynamic data masking so sensitive fields get redacted from unauthorized visibility. Encrypted columns and indexes then turn data unreadable without keys even in backups. Role hierarchy and attribute inheritance streamline applying policy nuance across user groups with reusable logic.
Finally, an embedded audit plugin tracks all structure changes with forensic details in tamper-proof format. Such capabilities help enforcement of regulatory policies like HIPAA and GDPR when working with personal information.
So while MySQL delivers capable security, MariaDB extends further for extremely strict confidentiality requirements.
Backup and Disaster Recovery Needs
Despite our best efforts at resilience, mission-critical databases require contingencies for data loss scenarios through:
- Application bugs erasing records
- Storage failures corrupting underlying files
- Power outages interrupting writes
- Severe weather disrupting infrastructure systems
Let‘s investigate how each platform equips us to prepare for worst case scenarios.
MySQL‘s Binary Logging
All MySQL editions incorporate binary log capabilities that persistently journal database alterations sequentially. By maintaining this crash recovery audit trail, DBAs apply changes from last viable backup alongside binary logs to restore continuity restoring up to the point corruption erupted.
For example, imagine a circumstance where…
- A valid total backup of a MySQL database exists from January 1 2023.
- A nasty mishap destroys the original database completely on March 1, 2023
- However, intact binary logs span January 1 to March 1 with all incremental transactions.
By restoring the January 1 backup then sequentially executing each binary log entry up until failure, I could reconstitute the database to March 1 dynamically. A life saver!
But while effective, rebuilding databases still incurs notable downtimes. Plus, corrupted backups provide zero salvation.
MariaDB Maximizes Availability
For enhanced resilience, MariaDB incorporates supplementary solutions sound enough to minimize the need for recovery:
Galera Cluster establishes multi-master database nodes that sync committed transactions securely across data centers. If any regional node gets knocked offline, integrated self-healing kicks-in immediately without reliance on manual failover.
MariaBackup performs regular incremental snapshots via filesystem mirroring rather than slower SQL dumps. Backups remain indefinitely mountable directly for availability unlike scripted restores. Sophisticated controls to specify frequencies, retention policies, compression and deduplication compress storage overheads further.
Such versatility explains MariaDB‘s prominence backing business-critical platforms at Boeing, HP Enterprise and Beyond Meat that treat uptime as utterly non-negotiable.
While few of us maintain infrastructure budgets on par with Fortune 500 behemoths, we equally value keeping our services accessible. If your use case demands extreme resilience, evaluate how MariaDB‘s durability toolkits reduce risks substantially compared to standard MySQL.
Key Takeaways Comparing MariaDB and MySQL
Friend, we‘ve now covered substantial ground contrasting MariaDB and MySQL – two exceptional database solutions. Let‘s recap the biggest differentiators:
Licensing – MySQL accommodates open source community needs alongside proprietary software teams. In contrast, MariaDB solely focuses on unconditional GPL open source consistency.
Architecture – MySQL powers the majority of deployments via the reliable InnoDB storage engine. Meanwhile MariaDB unlocks niche optimizations through specialized engines like Spider or Tokudb.
Performance – Both shine technically with well-tuned implementations for target workloads. MariaDB edges narrowly on benchmarks benefiting from tailored use case enhancements.
Security – MySQL delivers robust protections sufficient for most requirements. MariaDB extends further supporting state of the art encryption and access flexibility needed by highly regulated industries.
Resilience – MySQL supplies backbones like binary logging for crash recovery. MariaDB provides additional availability reinforcements via Galera multi-master clustering and instant restores with MariaBackup.
Of course, no single number ranks either database conclusively better overall. Your application priorities should guide selection based on which platform best fulfills your needs technically and philosophically.
Final Recommendations on Choosing Between MySQL and MariaDB
I recommend MySQL confidently for developers who:
- Already utilize MySQL broadly with satisfactory experiences
- Need certification that proprietary software will integrate easily
- Require tools compatible with advanced MySQL expertise existing internally
- Prefer maintaining relationships with Oracle-managed support systems
On the flip side, consider MariaDB ideal for organizations focused on:
- Commitment to consistent open source GPL development practices
- Pursuing niche storage engine advantages beyond one-size-fits all
- Leading edge performance enhancements proven through benchmarks
- Complying with strict security and privacy regulations
- Architecting for maximum possible uptime and instant failover
Of course, migration complexity matters too. Transitioning production database platforms warrants meticulous planning, which may rule out re-platforming fully in some environments.
When feasible, I typically suggest controlled trials first in lower risk development, reporting or shadow environments. Monitoring comparative proof points helps chart longer term adoption curves.
