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."
"For sure, the solution is very stable."
"The way that MySQL has improved my organization is that it comes free and also works fine on the technical side."
"However, it is easy to scale MySQL using the functions provided with the product."
"MySQL is a popular database platform for businesses because it is extremely easy to use."
"Compared to other databases, MySQL is cheaper and we were using the community edition which was free of cost. ML is fully integrated with the database in HeatWave. It has also many other features. MySQL is a far better solution in terms of pricing."
"The initial setup for the SQL database is not complex and it even integrates into the platform. You set up the recipe and then just follow the runbook, the build book. Then it works as long as you follow the procedures."
"One of the best features is this solution is easy to use."
"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."
 

Cons

"It could be more accessible for handling larger data sets."
"It would be beneficial if I could set a parameter and see different query mechanisms being run."
"MySQL tutorials and guides could be improved. Often they are too complex for someone with no database experience to understand."
"There are some issues with compatibility with Java environments that need to be improved. When Oracle bought this solution there were some driver changes that caused some issues with operations."
"The tool needs to improve table visualization."
"The replication needs improvement. It's becoming a native cloud product like Oracle DB or Cockroach DB."
"Security is a concern. MySQL could have better security features."
"When I run into issues, I really have to research how to fix them."
"Rather than going in-depth about the technical features, which a technical person can directly tell, I would say that MySQL should be able to adapt to the next framework. The 5G framework means an unstructured framework. So if MySQL becomes smoother and more adaptable, it'll be easier."
"The manuals or documentation could be better."
 

Pricing and Cost Advice

"It is an open-source tool."
"Faiss is an open-source solution."
"The solution’s pricing depends on customer requirements. A license is not required for the community edition."
"This is an open-source product that can be used free of charge."
"The pricing is not much expensive, it's cheap."
"The price of the solution is good because we have a good partner."
"The solution is open source so is free."
"It's an open-source database management system that can be used free of charge."
"Can range from free to quite expensive, depending on the environments and requirements, so better to really set goals ahead of setting it up."
"It is open-source."

Considering that there is a free version of MySQL, would you invest in one of the paid editions?

What is one thing you would improve with MySQL?
One thing I would improve related to MySQL is not within the product itself, but with the guides to it. Before, when it was free, everyone was on their own, seeking tutorials and how-to videos onli...
