Provides developer-friendly environment with robust security and cost-efficiency
The platform should provide a UI feature where users have the ability to manage it. The CockroachDB platform should have a chatbot where users can inquire about pricing or seek solutions for queries, rather than relying on email support. The current UI only provides SQL playground, which is technical. There should be a UI playground where users with limited technical knowledge can run and update queries, similar to phpMyAdmin or Adminer. Latency optimization could be improved for globally distributed applications, particularly in query routing. For multi-region deployment, CockroachDB requires at least three plus replicas across data centers to achieve strong consistency across regions, which increases infrastructure costs including compute, storage, and networking. The disadvantages include cost-efficiency with multi-region deployment and schema migration speed, which should be faster compared to other drivers. The query optimizer should handle complex queries better through the UI interface.

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

"I use CockroachDB to test big data samples and to create the best structure for databases. We have four users and required 10 people for deployment and maintenance."
"CockroachDB is excellent for managing relationships in RDBMS with multiple benefits such as the ability to create views and dynamic queries that save data and reduce the use of complex algorithms in code."
"The tool's most valuable feature is node syncing, which takes only 0.54 milliseconds."
"The subset of SQL that my client is using is completely supported."
"The most valuable features of the solution are its resiliency features and the geo-partitioning capabilities."
"The product has valuable security features."
"The most valuable feature is that CockroachDB is a distributed database, which can deploy nodes running in different regions."
"The availability and the easy to use feature is the most valuable. The documentation is also good."
"The product has better performance and stability compared to one of its competitors."
"I used Faiss as a basic database."
 

Cons

"The product must improve its disaster recovery features."
"For multi-region deployment, CockroachDB requires at least three plus replicas across data centers to achieve strong consistency across regions, which increases infrastructure costs including compute, storage, and networking."
"I think the engine itself could be improved. If you miss a partition key, it should be able to be modeled. This is where AI could be really helpful. For example, if a user is from Australia, the system should know to look for their data there first instead of searching in the US or another continent."
"We are looking for more features to support distributed high availability and geo-partitioning."
"The initial setup and pricing could be improved."
"The platform could be more extensible."
"I would like CockroachDB to have more compatibility with PostgreSQL, especially with the connection string and technical integrations."
"CockroachDB needs to improve store processes."
"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."
 

Pricing and Cost Advice

"The platform is affordable even for the enterprise version. It provides value for investment in terms of performance."
"The product's price depends on the user's company and the contract model they enter into with CockroachDB. Depending on the contract model one enters into with CockroachDB, the product may or may not be expensive."
"The pricing is good but can be made cheaper. I would rate the pricing a five out of ten."
"The solution's pricing is not cheap. However, the good thing is that customers are willing to pay for it if they want it."
"I've used CockroachDB at a small scale on the free accounts because we are only testing."
"Faiss is an open-source solution."
"It is an open-source tool."
