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

"We use MariaDB for identity provider services. Most of the things that we are doing are deployed in the container mode. All such solutions require a database, and MariaDB is easier to use for these kinds of deployments."
"One of the great features of MariaDB is its scalability. It's easy to handle even with large databases."
"What I like best about MariaDB is that it is open-source and reliable."
"The most valuable feature of MariaDB is the power it provides. It is a powerful solution."
"The most valuable features of the solution stem from the fact that it is a cloud-based tool, so it is pretty fast."
"This solution is user-friendly."
"MariaDB performs well as the backend database for our cloud-based telephony solution."
"Visual Studio offers unit testing integration and extensive searching capabilities."
"The solution provides complete support in terms of the SQL dialect and behaves nicely when it comes to transactions."
"PostgreSQL has complete SQL dialects and is useful for writing sophisticated and complex queries. We have experience with Oracle database. My partner is experienced in DDA and he writes sophisticated SQL queries. The solution helps to get the job done in the best possible way. In today’s age, most developers do not have strong SQL knowledge or language command. They find it difficult to write even a SQL statement. These developers write cool queries which perform badly on the database end. As DBAs, we constantly urge the developers not to write bad queries, help them learn more, and write placebo commands."
"It is easy to use."
"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."
"Initial setup is simple."
"The PostgreSQL database is similar to the SQL Server but has a slightly different technology that has similar resources as well. If the customer has the confidence using SQL Server, they will be fairly comfortable using this solution."
"It is very useful for both structured and unstructured data. You can store unstructured and structured data in PostgreSQL. It is easy to use. You can easily manage things through PostgreSQL Admin. It is cost-effective. Its on-premise version is free. It is agnostic of on-premise or cloud. You can install it on the cloud or on-premises. It is available with all clouds, and you can also install it on desktop or Windows Servers."
"PostgreSQL is very easy to use. I have experience in Oracle SQL and PostgreSQL uses the same syntax which makes it is easy for me to develop."
 

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."
"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 ability to create stored procedures in MariaDB is an area where the tool lacks a bit."
"There could be a command-line prompt for repairing the database and fixing indexes, similar to what was available in the old MyISAM storage engine."
"In the next release, I would like to see improvements in the scalability and redundancy features."
"The dashboard and pricing need improvement."
"MariaDB doesn't handle long or complex SQL queries quite as well as Oracle Database."
"The solution should do some fine-tuning on maybe the transaction per second so that users can get more than they can on the Microsoft SQL Server."
"I'm not really able to customize it."
"We often find the solution's datetime datatype challenging."
"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"A better graphic user-interface would be nice to see."
"It could be more secure."
"Sometimes, it becomes slow because of the network. So, there is room for improvement in performance."
"The solution needs to improve the query, documentation, and JSON data functionality."
"Integration with other platforms could be improved."
 

Pricing and Cost Advice

"MariaDB is available for free."
"It is free of charge."
"The cost is quite good. You can have the open source, free version, which has adequate capacity."
"It's an open-source 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."
"We pay for a yearly license."
"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."
"This is an open-source product, which can be used free of charge."
"It is an open-source platform."
"It is open source. There is no licensing."
"Affordable solution."
"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."
"We do not pay for licensing."
"It is free. There is no license on it."
"There is an annual license."
"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."

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.
