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 technical support of MariaDB is very helpful, and they came and tuned our queries with one-to-one assistance."
"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."
"It's a very easy product to set up."
"The solution runs very quickly. It's not slow at all."
"The most valuable feature of MariaDB is the power it provides. It is a powerful solution."
"I would say that for most use cases it works fine."
"The most valuable feature of the solution is the query speed it offers."
"MariaDB is a user-friendly solution. Performance wise, it's better than SQL. With SQL, I would need to write a number of queries. In contrast, MariaDB is light."
"It is very scalable and comes with a bonus: no licensing issues as you scale with your databases."
"We often use PostgreSQL for operations monitoring because we are a manufacturing company."
"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."
"It is easy to install and easy to manage. There is no license on it, so it is free. There is high compatibility with Oracle, and there are many tools for the migration of data from Oracle to Postgre."
"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."
"It is very simple to manage."
"PostgreSQL is very powerful, easy to manage, and has many features."
"The tool is user-friendly."
 

Cons

"It should work across all fields like SQLite, as it is the basis of any application, even apps for phones and the like."
"The license should be cheaper and closer to that offered by MySQL, Oracle and other products."
"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."
"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."
"In future releases, mainly the addition of security features would be beneficial for MariaDB."
"Lacks time series data and additional driving support would be helpful."
"The configuration could be improved. It should be easier."
"Maria DB has to improve from a management perspective."
"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."
"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."
"We often find the solution's datetime datatype challenging."
"The user interface could be a bit better."
"The pricing could be better."
"The performance of PostgreSQL could improve."
"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 could improve by adding data warehousing tools."
 

Pricing and Cost Advice

"MariaDB is an open-source software, meaning I don't need to pay for the product."
"The price of this solution represents a very good compromise between the cost and what it offers."
"The cost is quite good. You can have the open source, free version, which has adequate capacity."
"There is a monthly subscription to use MariaDB."
"MariaDB is available for free."
"This is an open-source product, which can be used free of charge."
"When it comes to MariaDB, it should have a more cost-effective license."
"We use the solution's free version."
"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."
"The licensing model is good."
"We do not pay for licensing."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"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."
"It is free. There is no license on it."
"PostgreSQL is a free and open-source database."
