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.

Native encryption ensures secure data management with a simple deployment

The most valuable feature is the on-premises data encryption facilities. By default, we can provide encryption, and this feature in MySQL is why we prefer it over other databases. The native encryption in MySQL encourages us to use this database model more frequently compared to Oracle and other databases. With Oracle, we have to buy another solution for encryption and masking, but MySQL supports native encryption, which enhances our return on investment. It perfectly supports our ROI, and we have no issues with its functionality.

Quotes from Members

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

Pros

"The performance is very good."

"It is very simple to install, and the commands are exactly the same as MySQL."

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

"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."

"It delivers fast processing times, particularly for frequent select queries and insert/update operations."

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

"Great monitoring and performance stability."

"Visual Studio offers unit testing integration and extensive searching capabilities."

More MariaDB pros

"When comparing MySQL to other solutions it is easier to use and boots up faster. Additionally, when you want to query a lot of data, MySQL is better in performance."

"The most valuable feature of MySQL is the informative error outputs of command line interface."

"Table partitioning is most valuable. It is easy to use."

"I like the simplistic view of MySQL to build custom queries and things like that as compared to SQL Server, which seems more cluttered. SQL Server has a query analyzer. MySQL pretty much does the same, and performance-wise, it has less overhead for connecting to our ERP system. It seems more responsive and cleaner. With MySQL, you get what you need without any overbloating, for which Microsoft is known. That's why they have so many constant security patches for everything because there is so much stuff, which degrades performance."

"MySQL gives us all of the critical features that we need in a database, but without the costs."

"MySQL is a scalable tool. Scalability-wise, I rate the solution a nine out of ten...The solution's technical support is good. I rate the technical support a nine out of ten."

"Support for enterprise-grade features like clustering, master-slave replication, even Sharding (to some extent) which is an advanced feature."

"We use it as a data store and from that perspective, we get everything we need."

More MySQL pros

"The performance is good."

"It is very simple to manage."

"The product is easy to use and works fast for relational databases."

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

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

"The solution is quite stable."

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

"The product's deployment is easy."

Cons

"When we have had issues with accidental computer shutdown or a power outage, our MariaDB database was corrupted."

"An improvement would be scaling it up to the levels of Oracle, especially when it comes to resilience, so that we can do higher transactions for two databases or power our operation."

"Document caching is an area of concern in the product, where improvements are required to help MariaDB improve on the previous queries as they are retained, and you can roll back to them."

"The features available are very basic."

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

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

"MariaDB can improve by adding more features. There are a lot of features, which are available in Oracle, and which are not available in MariaDB. We hope they will introduce the features soon."

"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."

More MariaDB cons

"At times, the autoscaling does not happen when there is a surge in load."

"We want high availability and replication features, which are currently missing in this solution. It would be great if they can provide an in-built replication feature, similar to Oracle RAC, in MySQL."

"The product is a little bit complex and it is difficult to find sufficient documentation."

"The documentation is pretty weak and should be improved."

"On the database side, it should be really lightweight, and the data structure should be like MongoDB."

"I would like to have features that allow us to jump between the cloud and our on-premises system."

"The workbench could be improved. In particular, error messages can be improved, which are horrific and completely unhelpful. I'd like to see improved parsing of errors. When you write SQL and it crashes, it usually is something completely irrelevant and not helpful. I've started to use GPT 3.5 for finding out how to do things. I got to do something a bit different, and that I found to be very useful. If there was some way to tie it into one of the new AI tools, that would probably be a good idea."

"I would like to see some improvements in the solution’s integration aspects."

More MySQL cons

"It needs more integration."

"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."

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

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

"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."

"Sometimes, the views create problems. If you don't have the view, sometimes what happens is you need to have the drivers properly set up for PostgreSQL."

"PostgreSQL’s performance could be improved."

"The user interface could be a bit better."

Pricing and Cost Advice

"MariaDB is available for free."

"The price could be less expensive."

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

"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."

"I used the open-source version, which is available free of charge."

"The cost is quite good. You can have the open source, free version, which has adequate capacity."

"We use the solution's free version."

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

More MariaDB pricing and cost advice

"I would rate the solution’s pricing a six out of ten. The solution is not cheap but it’s a fair value. The pricing depends on the use cases of our customers. Some of our customers use the community edition which is license free and a good fit for their use cases. However, we encourage our bigger customers to sign up because of the scalability issues. The paid versions get direct technical support from Oracle."

"We are using the free community version of the solution."

"MySQL is a cheap solution."

"There is a licensing cost because we are going for a proprietary product. There are some other versions for which there is no licensing cost."

"It's free."

"We are using the free community edition of MySQL."

"It is open source. We prefer it for POCs because it saves the license cost."

"I use the open-source free community version."

More MySQL pricing and cost advice

"The licensing model is good."

"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."

"We are using the free version of PostgreSQL."

"It is open-source. If you use it on-premise, it is free. It also has enterprise or commercial versions. If you go for the cloud version, there will be a cost, but it is lower than Oracle or Microsoft."

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

"It is an open-source platform."

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

"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."

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.”
