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

"MariaDB has a straightforward initial setup with easy-to-understand documentation."
"The most valuable feature of the solution is a relational database, which is fairly reliable...It is a stable solution."
"The stability of MariaDB is good, it has high availability."
"There is the need for a robust IDE for MongoDB. The existing PHP admin console doesn't meet the client's requirements effectively."
"MariaDB is scalable."
"Visual Studio offers unit testing integration and extensive searching capabilities."
"The solution is very easy to implement."
"From the user's perspective, the performance of the columnar queries is very good in terms of the database when comparing it to the Oracle, and MySQL."
"Scalable, stable, and easy to manage database system, with a straightforward installation."
"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."
"The solution has many valuable features such as it easy to use and the interface is intuitive."
"The product is easy to use and works fast for relational databases."
"The solution is open-source and free to use."
"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."
"What I like is that it's quite powerful in terms of performance."
"This is an open-source solution, operates at a high speed, and supports more than one SQL language."
 

Cons

"Data continuity could be improved."
"MariaDB could improve by adding support for non-relational structures and new data types."
"Replication could be better, and it's not so simple. It would be better if they had a replication server. It would make things a lot easier. You need to have that replication server, but not in the same server farm. Then there will be a bit of latency between both because you should have one in one city and another one in a different city. That kind of solution should be more baked into every single database today. Mirroring the database in a live environment where any record written on the production server replicates instantly across the fiber on the other server wasn't easy. Many people don't even bother with that, and they just run one server."
"A well-known issue for a lot of different users is associated with write-intensive applications."
"We'd like more data intelligence."
"MariaDB could be improved by adding more automation."
"It does not have tools for debugging procedures and functions."
"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."
"The interface could be much better."
"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."
"If it was free to use, it would be the perfect solution."
"It needs more integration."
"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."
"It could be improved by using parallelization. You want basically, distributed computing."
"We often find the solution's datetime datatype challenging."
"The pricing could be better."
 

Pricing and Cost Advice

"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."
"This is an open-source product, which can be used free of charge."
"This is an open source solution with no licensing fees."
"There is a monthly subscription to use MariaDB."
"We pay for a yearly license."
"We use the solution's free version."
"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."
"It is free of charge."
"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."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."
"The solution requires a license."
"There is an annual license."
"The need for our customers to pay for licences is contingent on their projects and budgets."
"It is free. There is no license on it."
"PostgreSQL is a free and open-source database."

Questions from the Community

What do you like most about MariaDB?
The integration with other products is seamless.
What is your experience regarding pricing and costs for MariaDB?
I have found the price of commercial MariaDB to be pretty steep, although not as high as Oracle. Customers often prefer the Community Edition because it's free.
What needs improvement with MariaDB?
The only potential area for improvement could be the pricing model, which might benefit from being more flexible or a bit cheaper.
How does Firebird SQL compare with PostgreSQL?
PostgreSQL was designed in a way that provides you with not only a high degree of flexibility but also offers you a cheap and easy-to-use solution. It gives you the ability to redesign and audit yo...
What do you like most about PostgreSQL?
It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping.
What is your experience regarding pricing and costs for PostgreSQL?
The tool is free of cost. For now, it's not about making money. But once we perfect it, we can offer it to customers willing to pay for support and other services. Most of my deployments are free.
