Monirul Islam Khan - PeerSpot reviewer
Head, Data Integration & Management at a non-profit with 10,001+ employees
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

"A consistent solution."
"Cassandra is good, it's better than CouchDB, and we are using it in parallel with CouchDB, as Cassandra looks better and is more user-friendly."
"Our primary use case for the solution is testing."
"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."
"Overall, I would rate Cassandra as nine because of its fast writes, which really suit our use cases mostly."
"Can achieve continuous data without a single downtime because of node to node ring architecture."
"I am satisfied with the performance."
"The time series data was one of the best features along with auto publishing."
"The platform's role-level security feature is quite effective for spatial data management."
"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 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."
"Supabase enables us to lower the skill floor while keeping the ceiling high."
"Supabase Vector rapidly increases the speed and efficiency with which I search through a database, helping with my data analysis tasks."
"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 has positively impacted our organization as it is very convenient since our business databases are already hosted in Supabase, making integration easy."
 

Cons

"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."
"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."
"Batching bulk data can cause performance issues."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"Cassandra could be more user-friendly like MongoDB."
"We found some issues with the batch inserts when the data volume is large."
"If you have a requirement of aggregation and joints, Cassandra doesn't support a solution that can give the aggregation."
"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."
"I notice that the schema visualizer can be improved. Additionally, the internal AI assistant powered by GPT can also be improved."
"Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start."
"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."
"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."
"It would be nice if all of this could be integrated all in one place with Supabase."
"I think there are still many Postgres features that can be developed further by the Supabase team."
 

Pricing and Cost Advice

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