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

"This solution is user-friendly."

"The most valuable feature of MariaDB is that it is open-source and we can easily migrate from other databases, such as Oracle to MariaDB."

"MariaDB is easy to install and is stable and scalable."

"The product has been stable and reliable."

"It is a stable solution."

"The performance is very good."

"What I like best about MariaDB is that it is open-source and reliable."

More MariaDB pros

"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 simple to manage."

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

"The tool is user-friendly."

"The built-in code procedural language is the most valuable. It has a built-in layer for code procedures. Its installation is very easy and quick, and it is free. It is also stable, and its performance is also good."

"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."

"We are able to create many different types of jobs and items with this solution making it one of the most valuable features."

"The solution is quite stable."

Cons

"The customer service and support are okay. But the response time is slow. Moreover, the material is not available freely."

"I would like to see a better user interface which would make the tool less complex."

"In the next release, I would like to see improvements in the scalability and redundancy features."

"The license should be cheaper and closer to that offered by MySQL, Oracle and other products."

"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."

"We'd like more data intelligence."

"Data continuity could be improved."

"MariaDB could be improved by adding more automation."

More MariaDB cons

"It could be more secure."

"We have to set up event API, which takes a lot of events from the user."

"PostgreSQL’s performance could be improved."

"It could be improved by using parallelization. You want basically, distributed computing."

"The user interface could be a bit better."

"I'd like to see better memory management. I think that that's one of the few areas that Postgres does not handle as well as MySQL does or did."

"When you get a large number of records in a database and start doing various queries, it can adversely impact the performance of the live running systems. That's an area we continue to look at and mean to improve, but it is not only because of PostgreSQL. It is also because of the way the schemas are put together, and certain events are triggered. So, it is because of both parties."

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

Pricing and Cost Advice

"MariaDB is available for free."

"The tool is open-source."

"MariaDB is an open-source software, meaning I don't need to pay for the product."

"There is a monthly subscription to use MariaDB."

"The price of this solution represents a very good compromise between the cost and what it offers."

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

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

"I rate the product's price a three on a scale of one to ten, where one is low price, and ten is high price since there are some support costs involved, even though it isn't an open-source solution."

More MariaDB pricing and cost advice

"There is an annual license."

"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."

"The community version of Postgre is basically free."

"It is open source. There is no licensing."

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

"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."

"The tool is cheaply priced compared to other RDBMS providers in the market."

"We are using the free version of PostgreSQL."

Overview

MariaDB is an open source relational database created by the original founders of MySQL. It is considered one of the most popular and trusted database servers throughout the world. MariaDB is a valued component found in most cloud offerings and is the default in many Linux tools. It is also widely used by Wikipedia, WordPress, and Google, among other well-known sites. Maria DB easily melds data into concise information from a vast array of applications, such as banking, online shopping, websites, and more.

MariaDB was originally created to improve MySQL performance. It is the most widely chosen database server due to the solution being super fast, robust, user-friendly, and easily scalable. MariaDB also offers a substantial ecosystem of plugins, storage engines, and numerous other valuable tools that make it very attractive for a significant offering of use cases.

The solution’s newest functionalities include compatibility with Oracle Database and Temporal Data Tables, and advanced clustering with Galera Cluster 4, which make it easier for users to research data history from any point in the past. Additionally, the most recent versions include JSON and GIS features. MariaDB is committed to staying an open source solution.

MariaDB Features

More storage: MariaDB works with more storage engines than MySQL and most other database servers available. Some storage options include, but are not limited to ARCHIVE, MERGE, CSV, MEMORY, BLACKHOLE, MyISAM, ColumnStore, MyRocks, and Cassandra.
Super fast: MariaDB offers faster authentication checks. The FlushSSL permits SSL certificates to be reloaded without a server restart, resulting in huge time savings.
Improved testing: MariaDB offers an extending testing suite that runs faster and can test more than ever before. Bugs can be easily fixed and invalid tests removed.

All fixed bug cases and development plans are completely public. MariaDB is a community-developed solution representing the true spirit of open source products.

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.”
