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.

AI Developer at a tech services company with 11-50 employees
Optimizing semantic search and RAG workflows has transformed decision-making efficiency
The serverless architecture is very cost-effective and best fit for minimum projects, with a standard plan of $50 per month that can be a hurdle for small enterprises. However, global constraints in the free tier allow usage in limited regions, US East 1 and AP South 1, and we do not expect everyone to be in the same place, which is a reason it can be improved. Pinecone uses eventual consistency; if I upsert a vector and immediately query it, it might not show up for a few seconds, which is a deal breaker for back-end use cases. The primary improvement I would like to see for Pinecone is the ability to switch. If there was an easier way to switch from one SaaS product to another, that would be great because as we scale, it is very difficult to transition from Pinecone to any other database. The easier the exit barrier, the easier the entry barrier for developers. I would like to see Pinecone develop a native semantic cache layer because gaps with competitors such as Redis, which built semantic caching that recognizes similar queries and returns cached answers instantly, would offer an improvement. As a back-end developer, I do not want to manage a separate Redis instance for caching LLM responses. If Pinecone could store and match frequently asked embeddings at the edge, it would drastically reduce our token costs and retrieval times. In addition, I would appreciate advanced query time consistency options. A strong consistency flag for specific namespaces, even if it costs more read units, would allow me to use Pinecone for more stateful and real-time back-end tasks rather than just static knowledge retrieval. I give Pinecone a rating of nine because I want to see more access and native model support. With the rise of multimodal AI, I would appreciate Pinecone supporting image-to-vector and audio-to-vector directly within Pinecone Inference service. Forcing developers to maintain separate pipelines for different data types adds architectural bloat, which can be streamlined to reduce latency. Google has launched multimodal embedding support, and if Pinecone could natively support converting any data type, such as images, audio, or text into vector embeddings, it would be greatly beneficial. At this time, Pinecone is doing very well. It would be great for Pinecone to include multimodal embedding capabilities so developers could utilize a single embedding model to ingest data from various sources such as text, audio, and image, which is increasingly necessary. With Google launching multimodal embedding capabilities, this addition would be important for every developer moving forward.

Quotes from Members

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

Pros

"Our primary use case for the solution is testing."
"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 most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"The solution's database capabilities are very good."
"Some of the valued features of this solution are it has good performance and failover."
"The time series data was one of the best features along with auto publishing."
"The use of Cassandra in real-time data analytics has been pivotal for our e-commerce platform. As our platform operates 24/7, providing services to sellers and customers alike, the need for real-time updates is paramount."
"A consistent solution."
"Pinecone's integration with AWS was seamless."
"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 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."
"We chose Pinecone because it covers most of the use cases."
"The product's setup phase was easy."
"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."
"The semantic search capability is very good."
"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."
 

Cons

"Doesn't support a solution that can give aggregation."
"We found some issues with the batch inserts when the data volume is large."
"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."
"Depending upon our schema, we can't make ORDER BY or GROUP BY clauses in the product."
"The solution is limited to a linear performance."
"Fine-tuning was a bit of a challenge."
"The disc space is lacking. You need to free it up as you are working."
"Maybe they can improve their performance in data fetching from a high volume of data sets."
"Pinecone uses eventual consistency; if I upsert a vector and immediately query it, it might not show up for a few seconds, which is a deal breaker for back-end use cases."
"For testing purposes, the product should offer support locally as it is one area where the tool has shortcomings."
"The tool does not confirm whether a file is deleted or not."
"Onboarding could be better and smoother."
"One major issue I have noticed with Pinecone is that it does not allow me to search based on metadata."
"One major issue I have noticed with Pinecone is that it does not allow me to search based on metadata."
"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."
"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."
 

Pricing and Cost Advice

"We are using the open-source version of Cassandra, the solution is free."
"We pay for a license."
"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."
"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."
"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."
"I think Pinecone is cheaper to use than other options I've explored. However, I also remember that they offer a paid version."
