Enhancing database learning with AI features and Oracle compatibility but needs performance improvements
I am a lecturer, and in universities, we use EDB Postgres Advanced Server to start with databases for practical purposes. I also assist with migrations, especially when clients want to migrate from Oracle to Postgres. So, while I am not a regular user, I am involved during migrations Since the…

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.

Quotes from Members

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

Pros

"The low cost and functionality allows us to save money on smaller database projects."
"Postgres is highly compatible with many software and programming languages. Its compatibility is excellent, covering nearly everything related to data engineering or migration."
"The number of indices available in Postgres is remarkable."
"I like that EDB Postgres Advanced Server scales well. A valuable feature of the solution is multi-tenancy support. It also supports JSONB."
"It gives us a solid, less expensive alternative to deploying with Oracle."
"I rate EDB Postgres Advanced Server's stability an eight out of ten."
"The feature of vector database management for AI is quite interesting and impactful."
"The product is user-friendly."
"The product has better performance and stability compared to one of its competitors."
"I used Faiss as a basic database."
 

Cons

"I have faced performance issues in the community edition."
"The product currently fails to offer a mobile application."
"There aren't specific new features we wish to add."
"An area for improvement in EDB Postgres Advanced Server is JSONB querying. It would be nice to have even stronger JSONB support from the solution."
"I would like to see improvements in the performance, especially in large-scale operations, as it currently cannot match Oracle's performance."
"The system is aging and not keeping up with the performance of new, enhanced database models."
"The security is not very robust and the product would be much more useful with more security options."
"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."
 

Pricing and Cost Advice

"I have been working on the community edition."
"Pricing is significantly lower than competing products."
"It is an open-source product."
"The product is either free with community support or very inexpensive with a small yearly fee for paid support."
"EDB Postgres Advanced Server is open source, so I don't pay for licensing."
"It is an open-source tool."
"Faiss is an open-source solution."
