Executive SummaryUpdated on Jan 23, 2025

MySQL and Faiss cater to different needs in technology infrastructure, with MySQL focusing on database management and Faiss on similarity search and clustering. MySQL has the upper hand in structured data management, while Faiss leads in fast vector-based searches.

Features: MySQL is known for ACID-compliance, robust indexing, and security, essential for structured data applications. It supports SQL queries and transaction processing. Faiss excels in swift similarity searches and machine learning on large datasets, providing high-dimensional nearest neighbor search capabilities, suitable for AI environments.

Ease of Deployment and Customer Service: MySQL offers comprehensive documentation and community support for straightforward deployment, assisted by numerous online resources. Faiss requires a deeper understanding of machine learning for effective deployment, lacking the extensive customer support seen with MySQL. Nonetheless, it remains a potent solution for knowledgeable users.

Pricing and ROI: MySQL, as an open-source solution, presents low initial costs and a high ROI, supported by its community-driven features. Faiss, also open-source, involves no direct software costs, but requires investment in expertise and infrastructure. Its ROI is contingent on its integration in AI-focused projects.

Integration improves accuracy and supports token-level embedding
The best features FAISS offers for my team include seamless integration with Colbert and the ability to use FAISS via the Ragatouille framework, which is tailor-made for using the Colbert model. Feature-wise, FAISS allows for more accurate result retrieval, and retrieval speed is also good when comparing the index size. Regarding features, I also emphasize that the usability of FAISS is very seamless, particularly its integration with Colbert and Ragatouille. FAISS has positively impacted my organization by helping us increase the accuracy of retrieval documents; when we store documents in token-level embedding, the accuracy will be high. Additionally, we do not need any external server to host FAISS, allowing us to integrate it with our backend framework, making it a very flexible framework.

Native encryption ensures secure data management with a simple deployment
The most valuable feature is the on-premises data encryption facilities. By default, we can provide encryption, and this feature in MySQL is why we prefer it over other databases. The native encryption in MySQL encourages us to use this database model more frequently compared to Oracle and other databases. With Oracle, we have to buy another solution for encryption and masking, but MySQL supports native encryption, which enhances our return on investment. It perfectly supports our ROI, and we have no issues with its functionality.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product has better performance and stability compared to one of its competitors."
"I used Faiss as a basic database."
"MySQL is an open-source product and has good community support. If you encounter any problem, you can easily ask other members of the community to help. They help you a lot. On top of being free, MySQL is a cross-platform database, meaning it can work on both Windows and Linux. It is very good for us."
"It is a very stable solution. I deployed the product six years ago, and it still works fine."
"It creates a unified view of the entire architecture and performance factor, helping to manage the network more easily."
"I rate the solution's stability a ten out of ten since it has been running flawlessly."
"My main reason for using MySQL for this small customer database company and for some kinds of scientific projects was that I had to do the installation myself. I didn't have a database administration team behind me. Therefore, I was looking for something very easy to handle. MySQL is easy to install, connect, and do all such things."
"The solution is very stable."
"For starters, it's free, which is always nice, and it's also pretty straightforward to use. It's a nice conventional database."
"This product is a good teaching tool for students who want to learn about networked databases."
More MySQL pros
 

Cons

"It would be beneficial if I could set a parameter and see different query mechanisms being run."
"One of the drawbacks of Faiss is that it works only in-memory. If it could provide separate persistent storage without relying on in-memory, it would reduce the overhead."
"It could be more accessible for handling larger data sets."
"MySQL lacks a feature akin to Oracle's Real Application Clusters, which ensures continuous database availability within the same data center or nearby data centers."
"The analytics features are in need of improvement."
"Scalability could be improved."
"Even for the best database, we always want the database to perform much better, so we wish MySQL would be much better, in terms of performance."
"Sometimes, not because the version is not the latest version, there are some issues with it. Sometimes there's an issue with the server which creates issues with it."
"​MySQL is not easily scalable on cost effective consumer grade hardware.​"
"Improvements are required in character set support, scalability, and big data sets."
"MySQL's performance requires attention. For optimal performance, one should review and sometimes revise the code, particularly when using server-side scripting."
More MySQL cons
 

Pricing and Cost Advice

"It is an open-source tool."
"Faiss is an open-source solution."
"I rate the solution's pricing as four out of ten, where one is cheap, and ten is expensive. For our basic needs, it's quite affordable. However, the cost increases when we need to scale up or require high availability. Our developer team of about 600 people uses MySQL without much issue. The pricing becomes more of a concern on the business side, as we have more end users and need constant database availability and scaling. In those cases, the solution gets a bit more expensive, even though it provides good value for the business."
"I use a free version at present."
"It has a community version."
"I would rate the solution’s pricing a six out of ten. The solution is not cheap but it’s a fair value. The pricing depends on the use cases of our customers. Some of our customers use the community edition which is license free and a good fit for their use cases. However, we encourage our bigger customers to sign up because of the scalability issues. The paid versions get direct technical support from Oracle."
"The solution’s pricing depends on customer requirements. A license is not required for the community edition."
"I don't pay for a license."
"MySQL is very cheap. It could be free. It also has a yearly licensing option."
"MySQL is cheaper than Microsoft SQL Server."
