Executive SummaryUpdated on Jan 12, 2025

PostgreSQL and MariaDB are prominent in the open-source database sector. PostgreSQL seems to have the upper hand with its comprehensive features and SQL compliance compared to MariaDB's focus on performance and integration.

Features: PostgreSQL excels with full SQL standard compliance, ACID compliance, and advanced data integrity. It provides robust support for complex queries and stored procedures. In contrast, MariaDB offers a pluggable storage engine architecture and performs well in read-heavy operations.

Room for Improvement: PostgreSQL users suggest enhancements in replication, partitioning, and query handling for COUNT(*). MariaDB could improve in write-intensive application support, clustering capabilities, and handling complex queries.

Ease of Deployment and Customer Service: Both PostgreSQL and MariaDB offer flexibility in deployment from on-premises to cloud environments. PostgreSQL has strong community support and documentation but lacks structured professional support, whereas MariaDB offers direct support options heavily reliant on community assistance.

Pricing and ROI: Both PostgreSQL and MariaDB are cost-effective open-source solutions. PostgreSQL's licensing cost reduction leads to high ROI, while MariaDB provides a favorable cost-benefit ratio with the community edition being a competitive alternative to proprietary databases.

Easy to deploy, cost-effective, and integrates seamlessly with other products

We had planned for an RDBMS version and not NoSQL. We use MariaDB Galera Cluster. It's a good product. It is cheap, scalable, performs well, and is efficient. We use GCP’s BigQuery for machine learning. We must follow the best practices of the tool. We missed some best practices like the storage engine and InnoDB. It was very difficult to identify why we were having performance issues. Then, we realized that some of our tables were still on MyISAM, the default storage engine. When we switched it back to the InnoDB, it was very smooth. InnoDB is the recommended one. We must follow the best practices given in the documentation during the initial setup. Overall, I rate the product a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."

"The solution's high availability is its most valuable aspect."

"The solution is very easy to implement."

"One of the great features of MariaDB is its scalability. It's easy to handle even with large databases."

"The most valuable feature of the solution is the query speed it offers."

"A valuable feature is that we can use it for quite a few things, all the things you'd expect from a server—along the lines of Linux's Lightweight Directory."

"Installation is straightforward."

"MariaDB is a fast and flexible tool."

More MariaDB pros

"It is very useful for both structured and unstructured data. You can store unstructured and structured data in PostgreSQL. It is easy to use. You can easily manage things through PostgreSQL Admin. It is cost-effective. Its on-premise version is free. It is agnostic of on-premise or cloud. You can install it on the cloud or on-premises. It is available with all clouds, and you can also install it on desktop or Windows Servers."

"It is very scalable and comes with a bonus: no licensing issues as you scale with your databases."

"It has completely met our needs. It works, and it is robust. We haven't had any problems with what PostgreSQL does for us and the way it does it. That's why we've been using it for so long. We understand it, and it does the job."

"The community support and the open-source community for it are good."

"The product is very similar to the SQL Server."

"The performance is good."

"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."

"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."

Cons

"The difficult part related to the product stems not from the tool itself but is related to learning how to implement the product in the right way without creating any wrong configuration that could cause security issues or performance issues."

"Master-master replication is something that needs to be simplified."

"I would like to see a better user interface which would make the tool less complex."

"The price could be less expensive."

"While MariaDB is a good relational database, it can be inflexible for complex use cases."

"The solution can improve by having support for more integration. However, at this time it is working well for us."

"Lacks time series data and additional driving support would be helpful."

"The only potential area for improvement could be the pricing model, which might benefit from being more flexible or a bit cheaper."

More MariaDB cons

"The interface climate could be better."

"The solution could improve the integration."

"Instead of the installation agent downloading all the packages for the install, it should allow the user to download the packages separately on their own to do the install."

"The pricing could be better."

"Postgres should focus on building a stronger knowledge base. They also need to expand their integration capabilities, so more tools and resources are available to manage it."

"As PostgreSQL is an open-source product, you do have to do a bit more configuration and management yourself."

"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."

"It could be more secure."

Pricing and Cost Advice

"MariaDB is available for free."

"We pay for a yearly license."

"When it comes to MariaDB, it should have a more cost-effective license."

"This is an open-source product, which can be used free of charge."

"The price of this solution represents a very good compromise between the cost and what it offers."

"The solution is free, but if you want the enterprise version you will need to pay for some licenses but the cost is less than other solutions, such as Oracle."

"MariaDB is a free-to-use solution."

"There is a monthly subscription to use MariaDB."

More MariaDB pricing and cost advice

"We are using the free version of PostgreSQL."

"The solution requires a license."

"There is an annual license."

"We use the open-source version of PostgreSQL and not the enterprise edition."

"The need for our customers to pay for licences is contingent on their projects and budgets."

"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."

"The community version of Postgre is basically free."

"It could be much cheaper. If you would like to build an application on Amazon today, PostgreSQL is the standard database with Redshift. If you want other databases, you can add them, but PostgreSQL is the basis of everything. It's a question of money, that's it."

Overview

MariaDB is an open source relational database created by the original founders of MySQL. It is considered one of the most popular and trusted database servers throughout the world. MariaDB is a valued component found in most cloud offerings and is the default in many Linux tools. It is also widely used by Wikipedia, WordPress, and Google, among other well-known sites. Maria DB easily melds data into concise information from a vast array of applications, such as banking, online shopping, websites, and more.

MariaDB was originally created to improve MySQL performance. It is the most widely chosen database server due to the solution being super fast, robust, user-friendly, and easily scalable. MariaDB also offers a substantial ecosystem of plugins, storage engines, and numerous other valuable tools that make it very attractive for a significant offering of use cases.

The solution’s newest functionalities include compatibility with Oracle Database and Temporal Data Tables, and advanced clustering with Galera Cluster 4, which make it easier for users to research data history from any point in the past. Additionally, the most recent versions include JSON and GIS features. MariaDB is committed to staying an open source solution.

MariaDB Features

More storage: MariaDB works with more storage engines than MySQL and most other database servers available. Some storage options include, but are not limited to ARCHIVE, MERGE, CSV, MEMORY, BLACKHOLE, MyISAM, ColumnStore, MyRocks, and Cassandra.
Super fast: MariaDB offers faster authentication checks. The FlushSSL permits SSL certificates to be reloaded without a server restart, resulting in huge time savings.
Improved testing: MariaDB offers an extending testing suite that runs faster and can test more than ever before. Bugs can be easily fixed and invalid tests removed.
Genuinely open source: Every code in MariaDB is GPL, LGPL, or BSD. Client libraries [for Windows (ODBC), Java (JDBC), or C] allow linking to closed source software. All fixed bug cases and development plans are completely public. MariaDB is a community-developed solution representing the true spirit of open source products.

Reviews from Real Users

Faustine C., Engineering Supervisor- Corporate Data Solutions and Services at TZ Telecoms Corporation, shares, “The software provides a lot of information on what is happening inside the database. For most performance parameters it is easy to know if something is not right in the configuration or optimization which helps engineers take remedial fine-tuning measures. For example, if the database is underperforming it is easy to know which performance parameter can be adjusted to handle the workload. It is difficult to troubleshoot database issues if many performance parameters can not be monitored or debugged which is the case with some database management systems. It provides great monitoring of data storage, processing, and performance stability which is really important for real-time data storage and processing. It's a user-friendly product.”

A PeerSpot user who is a Senior Engineer at a tech services company relates, “ The solution's high availability is its most valuable aspect. We have found the product to be stable and the initial setup is pretty simple. I'd rate the solution at a ten out of ten. I'm very happy with it overall. I would recommend the solution to others. It's easy to find details about the product online and to learn about it.”
