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.

More MariaDB pros

"The tool is user-friendly."

"Postgres is rock solid when deployed according to best practices as documented by the PostgreSQL community. When it's installed correctly, PostgreSQL is an enterprise-grade solution."

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

"PostgreSQL is very easy to use. I have experience in Oracle SQL and PostgreSQL uses the same syntax which makes it is easy for me to develop."

"With the database, you can provide a multi-component at the same service with the same performance, scalability, or all those things."

"It is very simple to manage."

"The solution is quite stable."

"It's a standard reliable database management system."

Cons

"I would like to see more compatibility going forward. This would help if there is a need to change databases."

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

"I am editing."

"MariaDB's GUI is an area with certain shortcomings where improvements are required."

"MariaDB could be improved by adding more automation."

"A well-known issue for a lot of different users is associated with write-intensive applications."

"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."

"MariaDB should provide HA and archive logging... I haven't had the opportunity to use the features provided by the solution since I don't know how to see them."

More MariaDB cons

"I'd like to see better memory management. I think that that's one of the few areas that Postgres does not handle as well as MySQL does or did."

"PostgreSQL could improve by providing a geographical solution for tracking trucks and people in the field. They might already have features similar to this and I have not found them. I haven't done research about this topic."

"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."

"It would be great if the solution offered even more integration capabilities."

"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."

"They need to have a better graphical interface. There is a tool called pgAdmin 4 that they use, which is free. It is written in Java, and it is slow. They need to have a better product that is similar to Toad for Oracle, but, of course, it is hard to get something that's really great and free. Other than that, it is great."

"They need to improve the user experience of the management."

"The search option is not very good."

Pricing and Cost Advice

"My company uses the free version of the solution."

"This is an open source solution with no licensing fees."

"It's an open-source solution."

"MariaDB is available for free."

"We use the solution's free version."

"The price could be less expensive."

More MariaDB pricing and cost advice

"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."

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

"The solution requires a license."

"Affordable solution."

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

"The tool is cheaply priced compared to other RDBMS providers in the market."

"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."

"It is an open-source platform."

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.”
