AI Developer at a tech services company with 11-50 employees

RAG pipelines have become faster and support teams handle fewer repetitive questions

The biggest area for improvement is scalability. Chroma needs better native support for distributed and multi-node deployments to complete enterprise-grade solutions. For millions of embeddings, it can struggle compared to more distributed solutions such as Pinecone and Weaviate. The querying and filtering capabilities can be more advanced, supporting complex Boolean logic and range operations on metadata. A more intuitive observability tool, including built-in dashboards for monitoring collection size, query performance, and index health, would be valuable for production use.The API could benefit from batch processing for bulk upserts and deletes, which can feel cumbersome at scale. Streaming ingestion would be a welcome addition. Documentation, while decent for getting started, lacks depth on advanced topics such as HNSW parameters optimization for specific embedding models in production environments and clear guidance. The community is still growing but remains relatively small compared to alternatives. Help on edge cases can be slow. A more structured forum, including an official Discord with dedicated support channels, would also be helpful.

Senior Data Engineer at a transportation company with 501-1,000 employees

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.

Quotes from Members

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

Pros

"Chroma has been a fantastic addition to our AI toolkit, and I genuinely believe it is one of the best entry points in the vector database space for any team getting started with RAG or semantic search."

"It's very easy to set up and runs easily."

"The solution's most valuable feature is its documentation, which allows new users to easily learn, deploy, and use it."

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

"ClickHouse provides responses within a few seconds, typically two to three seconds, which is impressive."

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

"We faced a challenge with deploying ClickHouse onto Kubernetes. Recently, we've been using ClickHouse Cloud, and the main issue is the high cost of the cloud service. The pricing isn't very competitive, especially for startups. I would instead buy a server and self-host if I have enough disk space. Besides that, ClickHouse has done very well, with clear goals and effective execution."

"Regarding performance, we tried multiple solutions when Kibana was failing, including PostgreSQL, MySQL, and even MongoDB for log ingestion of huge volumes, but ClickHouse outperformed all databases we tested, leading us to choose it for further use cases."

"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 open source with no vendor lock-in, providing excellent freedom to choose any vendor without restrictions."

"The main feature of ClickHouse is the optimizer because we had too many records to deduplicate, and the optimizer took this task by itself."

More ClickHouse pros

Cons

"The biggest area for improvement is scalability."

"I think Chroma doesn't have a ready-made containerized image available."

"The hybrid algorithm needs improvement."

"We would like to have fuzzy search capabilities in ClickHouse like we had with Kibana because there are scenarios where we cannot search keywords fuzzily in ClickHouse, whereas Elasticsearch allows that, and in such cases, Elasticsearch outperforms ClickHouse."

"Initially, I faced challenges integrating ClickHouse, particularly with inserting data from ActiveMQ, which caused duplicates. However, after adjusting the ClickHouse settings, the issue was resolved and there were no more duplicates."

"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 chose nine out of ten because, as I mentioned, the improvement side and the ten thousand partition limit created issues that we were hitting quite frequently, but with some schema manipulations we did manage to find a workaround, although that could have been avoided had things been better documented on how we could have solved this problem in a different approach, which took some bandwidth."

"My experience with pricing, setup cost, and licensing indicates that it is very expensive—ClickHouse is the most expensive option."

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

"One issue is that you need persistent volumes. Otherwise, if one system goes down, you lose data in that cluster."

"There aren't too many improvements I'd suggest for ClickHouse as it covers all my needs. There are just a few technical issues. For example, sometimes, when you want to get unique values and use certain tables, they don't work as expected. But it's not a major problem."

Pricing and Cost Advice

"The current version is an open-source."

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

"The tool is free."

"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."

"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."

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