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.
Harshwardhan Gullapalli - PeerSpot reviewer
AI Engineer at a educational organization with 51-200 employees
Semantic search has transformed financial document discovery and supports real-time RAG chat
On the integration side, Pinecone's Python SDK is straightforward. It integrates well with the usual AI stack like LangChain and LlamaIndex. That was smooth for me. Where it could improve is around documentation for edge cases. For instance, handling metadata filtering at scale, understanding the right embedding dimensions for different use cases, and best practices for indexing strategies. Those topics felt sparse in the documentation. More real-world tutorials specific to common patterns like RAG or recommendation systems would help developers ramp up faster. On support, the community is helpful, but if you hit something tricky and you are on a lower-tier plan, getting quick answers can be slow. Better-tiered support or more comprehensive troubleshooting guides would be valuable, especially for production deployments where latency is critical.

Quotes from Members

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

Pros

"I am satisfied with the performance; so far it has done fairly well and there haven't been any complaints."
"The most valuable features of this solution are its speed and distributed nature."
"We can add almost one million columns to the solution."
"Can achieve continuous data without a single downtime because of node to node ring architecture."
"Some of the valued features of this solution are it has good performance and failover."
"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"Cassandra has some features that are more useful for specific use cases where you have time series where you have huge amounts of writes. That should be quick, but not specifically the reads. We needed to have quicker reads and writes and this is why we are using Cassandra right now."
"A consistent solution."
"Pinecone was one of the earliest vector databases I came to know about, and it's the go-to option; I suggest it for anyone new to or learning about vector databases because it's very easy to start and work with without needing complex setups."
"Pinecone has positively impacted our organization by enhancing efficiency for the team, and the long-term effect has been that the chats have become much more personalized due to the memory added through a vector database."
"Pinecone is good for POCs and small projects because it's very easy to implement and very easy to use."
"The most valuable features of the solution are similarity search and maximal marginal relevance search for retrieval purposes."
"Pinecone helped us in achieving that, and we are now very fast and accurately generating outputs from our database."
"The best thing about Pinecone is its private local host feature. It displays all the maintenance parameters and lets us view the data sent to the database. We can also see the status of the CD and which application it corresponds to."
"Pinecone has positively impacted my organization by enabling fast similarity searches using metrics such as cosine or Euclidean distance on billions of vectors with low latency around 20 to 100 milliseconds, with key capabilities including hybrid search combining semantic and keyword, real-time updates, filtering, and re-ranking."
"Overall, the time to go through the documentation has drastically reduced, and Pinecone helps me save about two to three hours daily because of the manual effort required to go through the documentation."
 

Cons

"Cassandra could be more user-friendly like MongoDB."
"The disc space is lacking. You need to free it up as you are working."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"Interface is not user friendly."
"Fine-tuning was a bit of a challenge."
"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."
"There could be more integration, and it could be more user-friendly."
"Onboarding could be better and smoother."
"Pinecone is not open-source. The cost can escalate based on the pay-as-you-go pricing, so when there are high volume large embeddings, the cost would automatically rise."
"I want to suggest that Pinecone requires a login and API key, but I would prefer not to have a login system and to use the environment directly."
"If Pinecone gave us RAG as a service, we'd be more than happy to use that."
"I have not seen a specific outcome or metric of reduced costs since I started using Pinecone because it is very expensive compared to any other vector databases."
"The tool does not confirm whether a file is deleted or not."
"The major improvement I am expecting from Pinecone is increased vector size."
"The product fails to offer a serverless type of storage capacity."
 

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."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"I use the tool's open-source version."
"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."
"I have experience with the tool's free version."
"Pinecone is not cheap; it's actually quite expensive. We find that using Pinecone can raise our budget significantly. On the other hand, using open-source options is more budget-friendly."
"The solution is relatively cheaper than other vector DBs in the market."
"I think Pinecone is cheaper to use than other options I've explored. However, I also remember that they offer a paid version."
