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.

Offers simplicity and is cheaply priced
I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.

Quotes from Members

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

Pros

"Installation is straightforward."
"The documentation is quite straightforward."
"The solution is very stable. It was originally built under MySQL. It has a similar level of stability."
"I would say that for most use cases it works fine."
"The integration with other products is seamless."
"For non-production purposes. I'm just using it for my personal project, so it works quite well. I haven't faced any errors yet."
"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."
"The most valuable feature of MariaDB is the power it provides. It is a powerful solution."
"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."
"The product is very similar to the SQL Server."
"Scalable, stable, and easy to manage database system, with a straightforward installation."
"It's a standard reliable database management system."
"The solution is scalable, it is very good."
"The solution is open-source and free to use."
"It's a useful solution, that can be widely used."
"The main value is that it is open source, which means it is free. Our organization has the initiative to go to open source to cut down on cost. Oracle costs us $6 million a year right now, which is killing us, and Postgres costs nothing. So, there is a big push to go to Postgres."
 

Cons

"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."
"When we have had issues with accidental computer shutdown or a power outage, our MariaDB database was corrupted."
"The license should be cheaper and closer to that offered by MySQL, Oracle and other products."
"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 dashboard and pricing need improvement."
"The PL/SQL performance is slow if you have big batch jobs running overnight."
"In future releases, mainly the addition of security features would be beneficial for MariaDB."
"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."
"PostgreSQL could improve by being more user-friendly. In SQL Server they have a studio where you can easily do management but not in this solution."
"The price could be better."
"There could be a plugin to distribute the data on servers for the product."
"I have noticed that user and access management should be improved."
"I'm not really able to customize it."
"It could be improved by using parallelization. You want basically, distributed computing."
"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 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."
 

Pricing and Cost Advice

"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."
"The tool is open-source."
"We use the solution's free version."
"MariaDB is available for free."
"It is an open-source solution."
"I used the open-source version, which is available free of charge."
"We pay for a yearly license."
"The cost is quite good. You can have the open source, free version, which has adequate capacity."
"The solution requires a license."
"There is an annual license."
"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 also open-source so it is free."
"It is open source. There is no licensing."
"The need for our customers to pay for licences is contingent on their projects and budgets."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"Affordable solution."

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.
