Has maintained secure document storage and efficient data distribution with peer-to-peer architecture

The functions or features in Cassandra that I have found most valuable are that it is a distributed system similar to Mongo. It's good enough for comparison with another SQL database, so it's smooth and organized for distributed database system. The peer-to-peer architecture in Cassandra is helpful for network decentralization, and I have already introduced that feature. Cassandra features in peer-to-peer as well as another monitoring, so basically, it's good enough for our service. The tunable consistency level in Cassandra is good, and we are using that feature already. In terms of built-in caching and lightweight transactions in Cassandra, the transaction level is good, and it's optimized, so there are no more issues in that database. Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there. Additionally, the database monitoring system or auditing system is well-comparable with other database systems, so we are actually happy to be using this Cassandra database.

Vector search has reduced duplicate citizen proposals and empowers richer democratic participation

I had problems integrating the vector directly into Supabase, so I had to use Google Vertex to generate the embeddings and the information I needed in the database. It would be nice if all of this could be integrated all in one place with Supabase. I would prefer not to have to use a different or external tool to create these embeddings. It would be nice to have everything integrated in the same way. Apart from that, I think that is one of the cons I found, but it is basic. That was my main concern in that regard. My advice for others looking into using Supabase Vector is to take into account how you are going to create the embeddings, as it is not an option implemented straight away in Supabase. You will need to handle the embeddings with an external tool, so make sure to consider how these integrations are going to be made.

Quotes from Members

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

Pros

"The most valuable feature for us is the technical evaluation, it's the best technology."

"The technical evaluation is very good."

"It's used as our cloud based backend store as a temporary cache and for storing data that streams through our data pipe."

"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."

"Our primary use case for the solution is testing."

"Cassandra is a stable solution."

"We have experienced zero downtime using Cassandra, it is highly stable."

"The time series data was one of the best features along with auto publishing."

More Cassandra pros

"Supabase Vector rapidly increases the speed and efficiency with which I search through a database, helping with my data analysis tasks."

"The platform's role-level security feature is quite effective for spatial data management."

"Supabase Vector has positively impacted our organization as it is very convenient since our business databases are already hosted in Supabase, making integration easy."

"We completed what we initially estimated as a fifteen-day job in just three days, thanks to the Supabase dashboards and triggers."

"The most valuable part using Supabase Vector is how complex things I was able to build and deploy in a short period of time."

"Supabase Vector is easy to set up and cost-effective because the alternative is Firebase, which requires a credit card."

"Supabase Vector positively impacts my organization by reducing the cost of the LLMs."

"Supabase enables us to lower the skill floor while keeping the ceiling high."

Cons

"Cassandra could be more user-friendly like MongoDB."

"There were challenges with the query language and the development interface. The query language, in particular, could be improved for better optimization. These challenges were encountered while using the Java SDK."

"The interface could definitely be improved. It's a technical database and for me the features are not user friendly."

"We have had stability issues including out of memory issues and crashes with earlier versions of the product."

"Batching bulk data can cause performance issues."

"The solution doesn't have joins between tables so you need other tools for that."

"Row-level locking is not available; might be very helpful in update use cases."

"Fine-tuning was a bit of a challenge."

More Cassandra cons

"One area for the solution improvement is the inclusion of more sample code in various programming languages, particularly PHP."

"I think there are still many Postgres features that can be developed further by the Supabase team."

"One improvement I feel Supabase Vector could benefit from is that Supabase SDK stands out when comparing with a conventional Postgres SDK, and it would be even nicer if we could have a more direct way for access."

"I think the support system can be better because after Supabase Vector stopped working in India, there is no support."

"It would be nice if all of this could be integrated all in one place with Supabase."

"I notice that the schema visualizer can be improved. Additionally, the internal AI assistant powered by GPT can also be improved."

Pricing and Cost Advice

"We pay for a license."

"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."

"I don't have the specific numbers on pricing, but it was fairly priced."

"We are using the open-source version of Cassandra, the solution is free."

"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."

"I use the tool's open-source version."

"The solution's cost is reasonable compared to other solutions."
