Data observability has enabled real‑time analytics and cost savings but needs smoother inserts and cleanup

ClickHouse could be improved concerning data insertion, especially given the high amount of data handled. Constant efforts are made to optimize the features on its own, but with merges and inserts, only a single insert query can be performed allowing for the input of only 100,000 rows per second. It would be beneficial to insert more data and have configurations that are less user-operated. Ideally, ClickHouse would optimize itself to handle these processes automatically, reducing the need to contact the ClickHouse support team for infrastructure optimization. Additionally, delays are experienced when trying to delete databases with corrupt data, taking too much time and causing major outages, which necessitate contacting multiple teams across continents for resolution. The community surrounding ClickHouse also seems limited, providing a reliance on documentation, and there is a scarcity of developers working with ClickHouse, which hinders growth. If ClickHouse were more user-friendly and technically feasible, it would likely see greater expansion in usage.

Faced challenges with metadata filtering but have achieved reliable long-term memory for chat applications

We were looking at multiple options for a vector database, and we found Pinecone to be the easiest to integrate into our solution. Plus, it has a very generous free tier, which helps us as a startup. The best features Pinecone offers are quick setup and good indexing for us. The retrieval mechanisms are fast, and the integration with Python as with JavaScript and TypeScript libraries that Pinecone provides are very robust. Authentication is also very good. The namespaces feature allows us to break down or store data for each user separately, reducing interference and maintaining privacy as an important feature. 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 are seeing that the trainees getting trained on the platform are more satisfied with the results or messages generated by AI.

Quotes from Members

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

Pros

"It's easier to work with big data and calculations using the product."

"ClickHouse provides great query speeds because it is an OLAP database, so naturally, it provides higher speeds."

"ClickHouse has reduced our storage cost and improved our 99th percentile latency by 40%."

"The tool is column-based and infinitely scalable."

"If you have a real-time basis, you should take a look at ClickHouse because it works on a vector database, and the querying is super fast compared to traditional databases."

"There is no better option than ClickHouse in all OLAP-based databases, so I think it is best to use ClickHouse in that regard."

"ClickHouse has positively impacted my organization, as there was an entire exercise done on which database we were supposed to use for solving our problems, and we found ClickHouse was the one performing the best, which is when we adopted it."

"ClickHouse is much faster than traditional databases like MySQL and MongoDB. Its column-row searching strategy makes it very efficient. With ClickHouse, we can manage multiple databases, automatically insert data from other databases and delete data as needed. It supports real-time query performance, allowing simultaneous data insertion and retrieval. ClickHouse has improved significantly over the past two years, adding more functions and queries, as well as top functionality."

More ClickHouse pros

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

"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."

"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."

"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."

"In terms of return on investment, for our Hecta AI project, C-levels are typically spending 35 to 40 hours per quarter generating reports or understanding key metrics for decision-making, and after using Pinecone as a RAG database, we are able to cut this down to just about 10 minutes in a quarter for generating reports, achieving a reduction of about 95% of their time, allowing them to be more involved in decision-making rather than just finding information."

"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

"In terms of needed improvements, some enhancements in documentation are necessary."

"ClickHouse has its own concept of database triggers and doesn't support traditional database triggers."

"If you join our team, it should be easy for you to use ClickHouse, especially if you are a developer. However, you need to read the documentation and understand the problems you are trying to solve."

"The open-source version of ClickHouse is not very scalable."

"We had a lot of troubles while deploying a whole cluster."

"Too many issues exist for beginners to set up ClickHouse. Many parameters must be configured, such as maximum scatter part settings that determine when writing to a table stops."

"I would like ClickHouse to work more on integration with third-party tools."

"The main issue is the lack of documentation. Many features are available but are not fully documented, which can make finding information challenging."

More ClickHouse cons

"One major issue I have noticed with Pinecone is that it does not allow me to search based on metadata."

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

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

"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 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."

"Pinecone can be made more budget-friendly."

"Onboarding could be better and smoother."

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

More Pinecone cons

Pricing and Cost Advice

"We used the free, community version of ClickHouse."

"The tool is open-source."

"For pricing, if you use the self-hosted version, it would be free. Cloud services pricing would be an eight out of ten. I try to minimize costs but still have to monitor usage."

"ClickHouse has an open-source version, which is free to use and has almost all the features."

"The tool is free."

"If you have an in-house deployment on Kubernetes or something, it's going to be very cheap since you'll be managing everything."

"ClickHouse Cloud is not expensive compared to other databases, costing a few dollars per month while providing fast performance."

"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."

"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."
