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.

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.

Quotes from Members

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

Pros

"I used Faiss as a basic database."
"The product has better performance and stability compared to one of its competitors."
"It is a stable solution."
"The solution has PL/SQL compatibility."
"Visual Studio offers unit testing integration and extensive searching capabilities."
"It is an absolutely stable solution."
"MariaDB is a fast and flexible tool."
"The most valuable feature of the solution is the query speed it offers."
"A valuable feature is that we can use it for quite a few things, all the things you'd expect from a server—along the lines of Linux's Lightweight Directory."
"MariaDB is a user-friendly solution. Performance wise, it's better than SQL. With SQL, I would need to write a number of queries. In contrast, MariaDB is light."
 

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."
"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."
"MariaDB's GUI is an area with certain shortcomings where improvements are required."
"The GUI could be improved a bit. The user interface needs to be improved."
"MariaDB could improve by adding support for non-relational structures and new data types."
"It doesn't have the same level of maturity metrics as Postgres."
"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's not very stable. It needs improvement."
"The performance could be a bit better."
"Data continuity could be improved."
 

Pricing and Cost Advice

"It is an open-source tool."
"Faiss is an open-source solution."
"My company uses the free version of the solution."
"It's an open-source solution."
"The product is not expensive."
"I used the open-source version, which is available free of charge."
"We use the solution's free version."
"I rate the product's price a three on a scale of one to ten, where one is low price, and ten is high price since there are some support costs involved, even though it isn't an open-source solution."
"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."
"It is free of charge."
