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 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

"Ability to achieve write speeds 10k tps: Compared to existing, it is 300% percent higher."

"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."

"If you need availability and consistency, you can go with Cassandra."

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

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

"I am satisfied with the performance."

"The most valuable features are the counter features and the NoSQL schema, and it also has good scalability because you can scale Cassandra to any infinite level."

"Setup was very straightforward."

More Cassandra pros

"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."

"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."

"The most valuable feature of Pinecone is its managed service aspect. There are many vector databases available, but Pinecone stands out in the market. It is very flexible, allowing us to input any kind of data dimensions into the platform. This makes it easy to use for both technical and non-technical users."

"Pinecone's integration with AWS was seamless."

"We chose Pinecone because it covers most of the use cases."

"Pinecone has positively impacted my organization by helping people in needle-in-a-haystack situations, as previously they had to grind through PDF documents, PowerPoint documents, and websites, but now with Pinecone, they can ask questions and receive references to documents along with the page numbers where that information exists, so they can use it as a reference or backtrack, especially for things such as FDA approvals where they can quote the exact page number from PDF documents, eliminating hallucination and providing real-time data that relies on an external vector database with enough guardrails to ensure it won't provide information not in the vector database, confining it to the information present in the indexes."

"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."

"The most valuable features of the solution are similarity search and maximal marginal relevance search for retrieval purposes."

More Pinecone pros

Cons

"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."

"The solution is limited to a linear performance."

"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."

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

"Interface is not user friendly."

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

"Maybe they can improve their performance in data fetching from a high volume of data sets."

"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."

More Cassandra cons

"From a cost perspective, I believe Pinecone is a bit expensive compared to other solutions such as FAISS and Milvus, which are free and open source, while Weaviate is more cost-effective at scale, so I would request improvement in Pinecone's pricing structure."

"If Pinecone gave us RAG as a service, we'd be more than happy to use that."

"The product fails to offer a serverless type of storage capacity."

"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."

"Pinecone is good as it is, but had it been on AWS infrastructure, we wouldn't experience some network lags because it's outside AWS."

"The tool does not confirm whether a file is deleted or not."

"For testing purposes, the product should offer support locally as it is one area where the tool has shortcomings."

"If Pinecone could increase the free quota and not kill the free quota after seven days, that would be great."

More Pinecone cons

Pricing and Cost Advice

"We pay for a license."

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

"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."

"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."

"I think Pinecone is cheaper to use than other options I've explored. However, I also remember that they offer a paid 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 have experience with the tool's free version."
