Has supported web application data needs but requires design adjustments to manage complex queries efficiently
Complex queries in MariaDB where the query needs to parse thousands of lines or data values face some performance issues. For small and medium-size volume, it is pretty good. If it goes beyond certain data and complex queries, we see performance issues. We tried the advanced replication feature between different regions, replicating data specifically residing on MariaDB to two different regions of MariaDB data, and there were some technical snags in terms of slowness and longer processing time. Point-in-time recovery in MariaDB is good for small databases. When data volume increases beyond 5 GB or 10 GB per day or runs into double-digit GBs, we found some performance issues. For data below 10 GB, it works fine. Performance is the primary focus area for MariaDB, particularly during transactions or complex query jobs where slow performance is observed. MariaDB is scalable and easy to scale.

Real-time data capture optimizes database performance but Views create problems
One of the most valuable features is real-time data capture; it optimizes database performance. I think using real-time data capture reduces job running time and the amount of data sent at once with batch loads. Replicating the same data daily isn't optimal, so real-time reception improves application performance and reduces latency.

Quotes from Members

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

Pros

"The most valuable feature is that it uses multiple cores, which is better than some of the other databases."
"MariaDB performs well as the backend database for our cloud-based telephony solution."
"The product has good documentation and you can find many examples online."
"The most valuable features of the solution stem from the fact that it is an open-source product and offers its users great online community support."
"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."
"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."
"The most valuable feature of MariaDB is the replication mode."
"MariaDB is easy to install and is stable and scalable."
"We often use PostgreSQL for operations monitoring because we are a manufacturing company."
"What I like is that it's quite powerful in terms of performance."
"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."
"This is an open-source solution, operates at a high speed, and supports more than one SQL language."
"The performance is good."
"PostgreSQL makes it very adaptable to several descriptions of a record. Instead of having several tables or several relations for one entity, I can adapt this entity. It can be a multiform entity. For example, here in Mexico, a company and a person can be sold to us as a physical entity or a physical person."
"The tool is user-friendly."
"It is a pretty comprehensive database system. Its performance is good, and it does what it is supposed to do. It also integrates very well."
 

Cons

"I'd like to see improved materialized views, like the ability to save select queries. This feature is missing in MariaDB compared to other relational databases like Oracle and SQL Server."
"The PL/SQL performance is slow if you have big batch jobs running overnight."
"I would like to see more compatibility going forward. This would help if there is a need to change databases."
"The only potential area for improvement could be the pricing model, which might benefit from being more flexible or a bit cheaper."
"The dashboard and pricing need improvement."
"There is not much support available."
"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."
"It should work across all fields like SQLite, as it is the basis of any application, even apps for phones and the like."
"It needs more integration."
"It would be good to have machine learning functionality in this solution, similar to Microsoft SQL Server and other solutions. Machine learning capability for a basic level or a common user would be useful. It can also have good reporting capabilities."
"Integration with other platforms could be improved."
"They need to improve the user experience of the management."
"I have noticed that user and access management should be improved."
"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."
"The performance of PostgreSQL could improve."
"There are several features I would like to improve that aren't working as expected. It's likely that the latest version is doing something that was missed in the previous versions. For example, the output parameters — the stored procedures — is something new in PostgreSQL that Firebird has already had for a long time."
 

Pricing and Cost Advice

"The tool is open-source."
"This is an open source solution with no licensing fees."
"The price of this solution represents a very good compromise between the cost and what it offers."
"MariaDB is available for free."
"My company uses the free version of the solution."
"MariaDB is a free-to-use solution."
"The licensing cost is approximately $4000.00 per year and the licensing is based on the software and the number of posts that you make."
"There is a monthly subscription to use MariaDB."
"It is open source. There is no licensing."
"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 free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."
"There is an annual license."
"The licensing model is good."
"This solution can offer a cheaper choice for customers since it is open-source."
"It is free. There is no license on it."
"It is also open-source so it is free."
