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.

Semantic search has transformed client sites and drives faster projects with higher conversions

Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start. The SQL foundation, REST API, documentation, and integration with all the AI tools made it easier. However, understanding embeddings, index types, similarity metrics, and how SQL and vector hybrid queries work, as well as the RLS policies for vectors, required some time to learn. I do not have many things to point out, but a couple of areas for improvement come to mind. For index optimization guidance, clearer instructions on when to use IVFFlat versus HNSW indexes would be helpful. Additionally, having a built-in embedding generation capability would simplify the workflow, as currently, I use external services such as OpenAI or Hugging Face for that purpose.

Quotes from Members

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

Pros

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

"A consistent solution."

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

"The most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."

"The most valuable features of this solution are its speed and distributed nature."

"I'd rate the solution ten out of ten."

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

"Since I haven't had years of experience with it, it's still new to me. One valuable feature is its distribution, so I can run it partly in the cloud and part on-prem. That's a feature I'd like to use but haven't yet because we're trying to move to Azure. I don't know if or when that will happen. Ideally, we'd have it distributed over the cloud and on-prem simultaneously, so if something happens to our on-prem, we can keep going in the cloud, like a pay-as-you-go model with Azure."

More Cassandra pros

"Previously, 50% of searches returned no results or irrelevant products, but we changed that to 90% of searches returning relevant results, which led to a 30% increase in search-to-purchase conversions for the e-commerce client and was a big win for us."

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

"Using Supabase Vector, I was able to set it up in a couple of days, got it validated, and started working on building up the algorithm on top of that."

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

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

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

"I feel Supabase Vector is doing a very great job in reaching out to companies and helping them, and I believe every new entrepreneur who wants to build their own software product should be using Supabase Vector because I think it's the best vector database out there."

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

More Supabase pros

Cons

"One of the issues with the solution is that you cannot drop write like you're able to in MongoDB and MySQL, where you can join tables."

"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."

"Cassandra can improve by adding more built-in tools. For example, if you want to do some maintenance activities in the cluster, we have to depend on third-party tools. Having these tools build-in would be e benefit."

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

"The solution is not easy to use because it is a big database and you have to learn the interface. This is the case though in most of these solutions."

"The clustering needs to be better; it is getting there."

"Batching bulk data can cause performance issues."

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

More Cassandra cons

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

"When the website goes down, the lagging part needs to be resolved. When you have attached a front-end app and your users are using it and then the back-end is not in sync or lagging at the moment, it usually affects the front end of the app because the app will not be able to function to its maximum expectation."

"When setting up a database, a PostgreSQL instance, which is the most popular use of Supabase, instead of having to go and write and run an SQL line to create a pgvector on Supabase, it would be nice if the person creating the database for the project could just be asked with maybe a checkbox whether they want a vector database or not."

"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 feel Supabase Vector can be improved by venturing further into adding more backend features and maybe working with fast API frameworks like Python languages; they could improve and widen their capabilities."

"For advanced production use with millions of embeddings, it's necessary to be thoughtful about indexing such as HNSW or IVFFlat and hardware sizing to keep query times fast."

"My experience with Supabase Vector's performance at scale indicates that it operates excellently at small scales, but as we move toward larger scales, such as multi-million vectors, it requires careful engineering to maintain predictable performance, with challenges such as query plan complexity and latency variance."

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

More Supabase cons

Pricing and Cost Advice

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

"We pay for a license."

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

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

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

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

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