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.

Transaction processes are fast and good replication capability

Use cases include querying data warehouses and databases to fetch data for clients already working on PostgreSQL. We also use Postgres for building reports It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping. The query speed is fast, and the…

Quotes from Members

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

Pros

"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."

"The documentation is quite straightforward."

"We like the easy way that we can collect data from other databases."

"The solution has PL/SQL compatibility."

"What I like best about MariaDB is that it is open-source and reliable."

"I like the global transaction IDs (GTIDs) feature. It's quite reliable for replication between a master and a replica server, and it's a feature that MySQL also has but implemented differently."

"I haven't faced any technical issues with the product, and it works fine."

More MariaDB pros

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

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

"We are able to create many different types of jobs and items with this solution making it one of the most valuable features."

"The system can perform faster analysis by providing it with a lot of memory. Speed is crucial for analytics. Currently, the main reason we haven't adopted Elasticsearch is that we lack the necessary expertise to manage it."

"PostgreSQL is stable. It's available, stable, and reliable."

"The most valuable features are the price, stability, it is scalable and is used by our clients in small business environments, and it is a simple product to use."

"The solution has many valuable features such as it easy to use and the interface is intuitive."

"We often use PostgreSQL for operations monitoring because we are a manufacturing company."

Cons

"It doesn't have the same level of maturity metrics as Postgres."

"It would be good if they can maybe improve the mass import in the database. Currently, for importing a large number of data, we create a CSV file and upload all the things in the system. The system does not activate them by default. We have to do this manually. This may be due to the version we are using, but this is something we would like to see improved."

"The solution is not scalable."

"It does not have tools for debugging procedures and functions."

"One feedback I can quickly provide is the need for a robust IDE for MongoDB. The existing PHP admin console doesn't meet the client's requirements effectively."

"The stability could always continue to be improved upon."

"The GUI could be improved a bit. The user interface needs to be improved."

"There is room for improvement in terms of security."

More MariaDB cons

"It still needs to be more mature and have some backup feature. We are normally dealing with Oracle's data, and we have very strong online tools to back up the data and do other things. PostgreSQL still needs to do more in this area as well as in the high availability area. There are many external tools that you can use for PostgreSQL's high availability, but there is no embedded tool within PostgreSQL for high availability. It could have a feature similar to Oracle for working on a distributed system. It can have some scripts to improve the monitoring and some tools to do performance analysis. We have a workaround for most of such requirements except for the support for a distributed system, which is very difficult to have. This area should be included in the core of the database itself."

"Sometimes, it becomes slow because of the network. So, there is room for improvement in performance."

"A better graphic user-interface would be nice to see."

"I find it difficult to get connectors on the tool. For example, .NET has only one free provider in PostgreSQL. I need to pay the provider if I need something more sophisticated features. Other languages like PHP and Java have good community support. We need community support for .NET."

"It could be improved by using parallelization. You want basically, distributed computing."

"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."

"The user interface could be a bit better."

Pricing and Cost Advice

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

"The price could be less expensive."

"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."

"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 tool is open-source."

"It is an open-source solution."

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

More MariaDB pricing and cost advice

"It is free. There is no license on it."

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

"It is an open-source platform."

"It is also open-source so it is free."

"The solution requires a license."

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

"This solution can offer a cheaper choice for customers since it is open-source."

"It is open source. There is no licensing."

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.”
