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

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

"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."

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

"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 Cloud saves a lot of time for our DevOps engineers since there isn't much deployment involved and everything is served directly, leading to increased efficiency and productivity."

"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."

"The tool's most valuable feature is a database. It supports portal APIs and offers good flexibility."

"The best thing about the tool is that I can set it up on my computer and run queries without depending on the cloud. This is why I use it every day."

"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."

"With ClickHouse, since data is stored in a columnar way, we get aggregation functions that are much faster than transactional databases, such as SQL Server, and the cost efficiency is also much reduced compared to Cosmos DB since we use it on-premises, the cost is nearly cut, which is very useful for us."

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."

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

"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."

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

"In terms of improvements, it's not designed for very frequent small writes, making it less scalable in write-intensive workloads, and it's not flourishing in transactional use cases or when ingesting streaming data, such as batching or buffering, which is something ClickHouse will improve."

"ClickHouse could be improved with self-hosting capabilities and better documentation for how to host it at scale."

"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 aggregation capability is a valuable feature. It's highly efficient, allowing us to review entire transaction histories and user activities in the market. We've tried MongoDB, Postgres, MariaDB, and BigQuery, but ClickHouse is the most cost-efficient solution for collecting data at high speeds with minimal cost. We even used ClickHouse Cloud for a month, and it proved to be a great setup, especially for startups looking to handle big data. For example, if there is a need for 2-4 terabytes of data and around 40 billion rows with reasonable computing speed and latency, ClickHouse is ideal. Regarding the real-time query performance of ClickHouse, when using an API server to query it, I achieved query results in less than twenty milliseconds in some of my experiments with one billion rows. However, it depends on the scenario since ClickHouse has limitations in handling mutations. Additionally, one of ClickHouse's strengths is its compression capability. Our experimental server has only four terabytes, and ClickHouse effectively compresses data, allowing us to store large amounts of data at high speed. This compression efficiency is a significant advantage of using ClickHouse."

Pricing and Cost Advice

"The current version is an open-source."

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

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

"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."

"The tool is open-source."

"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."
