Executive SummaryUpdated on Jun 3, 2026

MariaDB and Milvus compete in the database management space, with MariaDB specializing in traditional relational databases and Milvus focusing on vector similarity search. MariaDB has an advantage in cost-effective relational data handling, while Milvus excels in advanced vector processing for specialized applications.

Features: MariaDB provides features like scalability, complex querying, and robust security, making it suitable for handling significant relational data tasks. Milvus, on the other hand, supports large-scale data indexing, real-time similarity search, and seamless integration with machine learning frameworks, making it ideal for specialized data processing tasks.

Room for Improvement: MariaDB could enhance its vector handling capabilities and offer more seamless integrations with emerging technologies. Additionally, it may benefit from improved user interface designs and performance monitoring tools. Milvus could improve its user-friendliness for those new to vector databases, optimize the learning curve, and expand its integrations with additional data processing tools.

Ease of Deployment and Customer Service: MariaDB is straightforward to deploy, leveraging SQL familiarity for easy integration and setup with existing systems. Its established customer service is a significant benefit. Milvus uses a flexible cloud-native deployment model but may present a learning curve due to its specialized nature. Its customer support is tailored to its niche focus.

Pricing and ROI: MariaDB typically has lower initial setup costs, appealing to businesses managing relational databases. In contrast, Milvus requires a higher investment, justifiable by its advanced vector processing capabilities, offering substantial ROI in data-intensive applications requiring specialized analysis.

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.

Provides quick and easy containerization, but documentation is not very user-friendly

Milvus' documentation is not very user-friendly and doesn't help me get started quickly. Chroma DB provides super user-friendly documentation, enabling new users to get started quickly. Chroma DB's setup doesn't have many dependencies, whereas Milvus usually comes with some dependencies because of the way it needs to be deployed. Unlike Milvus, it's very easy to do POCs with Chroma DB.

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 solution runs very quickly. It's not slow at all."

"The product has been stable and reliable."

"The solution is very easy to implement, the product makes it very easy to use as a primary database or a standby database, and the switches are easy to use."

"MariaDB can solve things better than MySQL, and MariaDB has better performance than MySQL."

"One of the great features of MariaDB is its scalability. It's easy to handle even with large databases."

"It delivers fast processing times, particularly for frequent select queries and insert/update operations."

"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."

More MariaDB pros

"The solution is well containerized, and since containerization is quick and easy for me, I can scale it up quickly."

"Milvus offers multiple methods for calculating similarities or distances between vectors, such as L2 norm and cosine similarity. These methods help in comparing different vectors based on specific use cases. For instance, in our use case, we find that the L2 distance works best, but you can experiment with different methods to find the most suitable one for your needs."

"The best feature of Milvus was finding the closest chunk from a huge amount of data."

"I like the accuracy and usability."

"Milvus has good accuracy and performance."

Cons

"The stability could always continue to be improved upon."

"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."

"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."

"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."

"The GUI could be improved a bit. The user interface needs to be improved."

"It would be good if they can maybe improve the mass import in the database."

"It would be good to have tools for debugging procedures and functions."

"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."

More MariaDB cons

"I've heard that when we store too much data in Milvus, it becomes slow and does not work properly."

"Milvus could make it simpler. Simplifying the requirements and making it more accessible. It could be more user-friendly."

"Milvus' documentation is not very user-friendly and doesn't help me get started quickly."

"Milvus has higher resource consumption, which introduces complexity in implementation."

Pricing and Cost Advice

"It is free of charge."

"The tool is open-source."

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

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

"The product is not expensive."

"I used the open-source version, which is available free of charge."

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

"It's an open-source solution."
