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.

Reliable open-source database has supported our migration and improved e-commerce performance

Percona Server seems great to me overall. If I had to think of any small area for improvement for Percona Server, it would be around the proxy story. When adding a proxy to manage traffic better, we first tried SQL Proxy, but it never really worked for us, which was unfortunate because SQL Proxy offers better optimizations for read performance. We did have success with HAProxy, but it works on a network level, while SQL Proxy was designed to be SQL-aware and distribute parts of the query across the database cluster. The performance gain we were hoping for with SQL Proxy did not materialize, so we remained on the network level with HAProxy. Databases can be finicky regarding the performance they need. We had some disk I/O latency issues, which led us to use different types of nodes in our Kubernetes cluster where we provisioned Percona Server explicitly. There is a lot of IOPS happening under the hood, and while I suspect the application was not very efficient, it was also challenging to identify that we were experiencing performance issues due to disk performance. It would be helpful to clarify the metrics related to disk I/O latency so we could understand where our bottlenecks are.

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."

"After switching to Percona Server, we were able to resolve those issues quickly."

"We find the product mostly stable."

"Percona Server has positively impacted my organization by reducing downtime for applications and improving backup capabilities."

"Percona Server's scalability is very strong, as it features thread pooling for over 10,000 connections, scales out horizontally, and comes with XtraDB Cluster and ProxySQL, making it very effective."

"Percona Server has positively impacted my organization because it is open source, and if the official MongoDB goes in different directions or makes its product expensive, we can still use Percona Server, which serves as a sort of safety net."

"In my use of Percona Server, I've found that the replication and High Availability features are the most valuable."

Cons

"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."

"It would be beneficial if I could set a parameter and see different query mechanisms being run."

"Percona Server could be improved to keep pace with other flavors of MySQL, such as MariaDB, and could pivot to be Percona Server for MariaDB given Oracle's reduced investment in MySQL recently."

"If I had to think of any small area for improvement for Percona Server, it would be around the proxy story."

"Percona Server could be improved by adding more advanced query fields, which would be very helpful."

"It doesn't reclaim disk space when rows are deleted."

"I also think there should be more use cases and documentation on deploying in Kubernetes with real-life examples, as currently, the documentation is minimal, making it difficult in a production situation."

"If Percona had flashback capabilities, it would be ideal."

Pricing and Cost Advice

"Faiss is an open-source solution."

"It is an open-source tool."
