Explore innovative database indexing and distributed architecture capabilities
The number of indices available in Postgres is remarkable. Additionally, the way it forks each process into a child node, instead of executing in the same node, is quite different from most databases. These features can be especially useful in certain scenarios compared to MySQL or other SQL-based databases. Also, the ability to distribute the database across different machines is a significant advantage.

Vector search has improved e‑commerce relevance but setup and learning curve still need work
Vespa definitely had its own set of challenges. It was really hard to get into initially, especially when I started implementing it in 2024 along with one junior employee, and the lack of documentation made it difficult. I aimed for an implementation with ColBERT, a sparse embedding mechanism, which I believed would fit well for e-commerce. We went through iterations during A/B testing because the initial set did not work as expected, which extended the process to about one and a half years. Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it. Community support was decent, and we turned to it for clarifications. However, substantial improvements in documentation are necessary, especially more examples for handling DSL effectively. Having a runtime testing feature would greatly facilitate quick iterations.

Quotes from Members

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

Pros

"This product has allowed us to reduce costs in some parts of our infrastructure without losing functionality."
"The low cost and functionality allows us to save money on smaller database projects."
"The product is user-friendly."
"Major reduction in run cost, and a quantum leap in the flexibility of deployment models Elimination of replication of transaction from reporting systems Able to do rolling upgrades with zero production downtime."
"I like that EDB Postgres Advanced Server scales well. A valuable feature of the solution is multi-tenancy support. It also supports JSONB."
"I would highly recommend EDB Postgres Advanced Server to others."
"Cost/benefit wise Postgres is a great solution."
"I rate EDB Postgres Advanced Server's stability an eight out of ten."
"Vespa is very good and it improves our product, and we got more clients."
"While conducting A/B testing, Vespa seemed to be performing slightly better than Elasticsearch, especially in search relevancy within live production systems, and its performance was decent."
"The best feature to me is the LTR feature, the ranking feature to be specific."
 

Cons

"There aren't specific new features we wish to add."
"The lack of additional security features is really the thing that makes the product less useful."
"I would like to see improvements in the performance, especially in large-scale operations, as it currently cannot match Oracle's performance."
"The security is not very robust and the product would be much more useful with more security options."
"Lighter integration model for containerized deployment. Effectively, there still remain some issues with a containerized deployment, so we have opted for a non-containerized deployment."
"The product currently fails to offer a mobile application."
"Setting up MySQL is slightly more straightforward than Postgres."
"I have faced performance issues in the community edition."
"We want Vespa to implement some UI features so that we can visualize how our data goes and what embeddings it stores."
"Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it."
"The integration is actually a pain."
 

Pricing and Cost Advice

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