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.

Cloud deployment has improved security and performance but still needs richer query features

MariaDB is easy to install. Performance of MariaDB has improved with the query optimizer. We use MariaDB's data-at-rest encryption. Encryption is available in MariaDB, so we are secure for transmitting data without concern about moving over networks. Query optimization in MariaDB is better than Oracle. We use advanced replication for MariaDB. Role-based access is available in MariaDB, which is a good feature. The technical support of MariaDB is very helpful. They came and tuned our queries with one-to-one assistance.

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

"It is very simple to install, and the commands are exactly the same as MySQL."

"The solution is stable and the performance is good."

"I haven't faced any technical issues with the product, and it works fine."

"I like the global transaction IDs (GTIDs) feature. It's quite reliable for replication between a master and a replica server, and it's a feature that MySQL also has but implemented differently."

"With MariaDB, you can use it as a column store database, which means you replicate your transactional data as columnar data and then you can use it as a sort-of business intelligence, and it's a very easy product to set up."

"The solution is very stable. It was originally built under MySQL. It has a similar level of stability."

"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 solution's high availability is its most valuable aspect."

More MariaDB pros

"Milvus has good accuracy and performance."

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

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

"I like the accuracy and usability."

"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."

Cons

"It doesn't have the same level of maturity metrics as Postgres."

"I would like to see more compatibility going forward. This would help if there is a need to change databases."

"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."

"There is not much support available."

"Master-master replication is something that needs to be simplified."

"A well-known issue for a lot of different users is associated with write-intensive applications."

"The difficult part related to the product stems not from the tool itself but is related to learning how to implement the product in the right way without creating any wrong configuration that could cause security issues or performance issues."

"It should work across all fields like SQLite, as it is the basis of any application, even apps for phones and the like."

More MariaDB cons

"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."

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

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

Pricing and Cost Advice

"It's an open-source solution."

"When it comes to MariaDB, it should have a more cost-effective license."

"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."

"The product is not expensive."

"MariaDB is available for free."

"It is an open-source solution."

"This is an open source solution with no licensing fees."

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