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

"Some of the valued features of this solution are it has good performance and failover."
"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."
"The solution provided us with more than 100K PNRs a second and because the company was international there was a heavy data write, and at the same time a heavy data read."
"Cassandra is a stable solution."
"The most valuable feature of Cassandra is its fast retrieval. Additionally, the solution can handle large amounts of data. It is the quickest application we use."
"We can add almost one million columns to the solution."
"It's used as our cloud based backend store as a temporary cache and for storing data that streams through our data pipe."
"The time series data was one of the best features along with auto publishing."
"Supabase Vector positively impacts my organization by reducing the cost of the LLMs."
"The most valuable part using Supabase Vector is how complex things I was able to build and deploy in a short period of time."
"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 enables us to lower the skill floor while keeping the ceiling high."
"The platform's role-level security feature is quite effective for spatial data management."
"When I got to know about Supabase Vector, I fell in love with it since it worked for what I was using it for, and I just stuck to it."
"Supabase Vector positively impacts my organization through major improvements in search relevance, faster development speed, a simpler architecture, and reduced engineering overhead, with better performance in real queries due to the hybrid SQL plus vector search."
"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."
 

Cons

"Depending upon our schema, we can't make ORDER BY or GROUP BY clauses in the product."
"Cassandra could be more user-friendly like MongoDB."
"Row-level locking is not available; might be very helpful in update use cases."
"If you have a requirement of aggregation and joints, Cassandra doesn't support a solution that can give the aggregation."
"The initial setup of Cassandra can be difficult in the configuration. There might be a need to have assistance. The implementation process can six months for connecting to certain databases."
"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."
"Some issues arise from our vendors like Apache slowness and distribution or load balancing from HAProxy, which should better handle consumption for high-level concurrency."
"Fine-tuning was a bit of a challenge."
"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."
"Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start."
"I notice that the schema visualizer can be improved. Additionally, the internal AI assistant powered by GPT can also be improved."
"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."
"I think the support system can be better because after Supabase Vector stopped working in India, there is no support."
"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."
"One area for the solution improvement is the inclusion of more sample code in various programming languages, particularly PHP."
 

Pricing and Cost Advice

"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"I don't have the specific numbers on pricing, but it was fairly priced."
"I use the tool's open-source version."
"We pay for a license."
"We are using the open-source version of Cassandra, the solution is free."
"The solution's cost is reasonable compared to other solutions."
