Provides quick query search and has a big database
I did not face any issues integrating Faiss with other tools. I would recommend the solution to other users. Faiss has facilitated my AI-driven project very well. I recommend that other users use it for their AI projects because it provides quick query search and has a big database. Overall, I rate the solution nine and a half out of ten.
Muzzamil  Hussain - PeerSpot reviewer
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."
"I would use MySQL for a medium project, with around 1,00,000 hundred thousand users, because of the indexing and stored procedures."
"Setup is easy. MySQL of various flavours has community editions to easily test, deploy, and run.​"
"I find MySQL's relational data storage format very useful for data management. Our structure is well-defined and easy for end users and business stakeholders to read. I appreciate the tool's simplicity and ability to integrate with our backend tools."
"What I've been most pleased with is the cost point, performance, and ease of use."
"The tool is open-source and there is no cost involved in its use."
"It has a community version. When I have to create a new database, I have no problems with licenses."
"We are completely comfortable with the database’s performance and it is a mature product. My organization was looking for an open-source database for our smaller customers like the community edition. For bigger customers, we can scale into commercial and supported editions."
"We use it as a data store and from that perspective, we get everything we need."
 

Cons

"It would be beneficial if I could set a parameter and see different query mechanisms being run."
"It could be more accessible for handling larger data sets."
"When I run into issues, I really have to research how to fix them."
"The licensing cost of the solution is expensive, which MySQL needs to consider improving."
"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."
"Improvements to MySQL depend on the specific use case. For example, in my scenario, I frequently need to maintain and store data, which can then be utilized to generate reports. On the other hand, others may suggest incorporating a feature that allows for easier visualization of the data, such as what is available in Power BI or other similar tools."
"We have encountered some performance issues, and the solution takes time for performing complex queries."
"The workbench could be improved. In particular, error messages can be improved, which are horrific and completely unhelpful. I'd like to see improved parsing of errors. When you write SQL and it crashes, it usually is something completely irrelevant and not helpful. I've started to use GPT 3.5 for finding out how to do things. I got to do something a bit different, and that I found to be very useful. If there was some way to tie it into one of the new AI tools, that would probably be a good idea."
"I would like to see more integrations of the solution with other platforms and improve the support on different data types."
"Clusters are hard to perform so we use no SQL alternates like MongoDB."
 

Pricing and Cost Advice

"Faiss is an open-source solution."
"It is an open-source tool."
"There is not a license required for this solution."
"MySQL is a free and open-source solution."
"MySQL is a cheap solution."
"There is a licensing cost because we are going for a proprietary product. There are some other versions for which there is no licensing cost."
"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."
"When you know the setup will continue to grow, make sure you have the paid support."
"It's free."
"I am using the Community Edition, which is available free of charge."
