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.

Student at a university with 10,001+ employees

Explore innovative database indexing and distributed architecture capabilities

The number of indices available in Postgres is remarkable. Additionally, the way it forks each process into a child node, instead of executing in the same node, is quite different from most databases. These features can be especially useful in certain scenarios compared to MySQL or other SQL-based databases. Also, the ability to distribute the database across different machines is a significant advantage.

Quotes from Members

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

Pros

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

"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."

"ClickHouse is very easy to use; one of the good features is that it has joins, which were not present in Druid, and Druid was quite expensive, especially with our applications at Sam's Club utilizing ClickHouse very quickly."

"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."

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

"ClickHouse is a user-friendly solution that tries to be compatible with SQL standards."

"We moved away from Redshift to ClickHouse because of the integration and the flexibility that it provides, which best suited our use case."

"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."

More ClickHouse pros

"The product is user-friendly."

"I like that EDB Postgres Advanced Server scales well. A valuable feature of the solution is multi-tenancy support. It also supports JSONB."

"I rate EDB Postgres Advanced Server's stability an eight out of ten."

"The low cost and functionality allows us to save money on smaller database projects."

"The backup utility tools such as pg_restore and pg_dump are really convenient and efficient tools to handle backup and recovery."

"The number of indices available in Postgres is remarkable."

"The feature of vector database management for AI is quite interesting and impactful."

"It gives us a solid, less expensive alternative to deploying with Oracle."

Cons

"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."

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

"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."

"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."

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

"ClickHouse could be improved further in several areas."

"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."

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

More ClickHouse cons

"Setting up MySQL is slightly more straightforward than Postgres."

"An area for improvement in EDB Postgres Advanced Server is JSONB querying. It would be nice to have even stronger JSONB support from the solution."

"The product currently fails to offer a mobile application."

"I have faced performance issues in the community edition."

"There aren't specific new features we wish to add."

"The security is not very robust and the product would be much more useful with more security options."

"The system is aging and not keeping up with the performance of new, enhanced database models."

"I would like to see improvements in the performance, especially in large-scale operations, as it currently cannot match Oracle's performance."

Pricing and Cost Advice

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

"The tool is open-source."

"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."

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

"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 product is either free with community support or very inexpensive with a small yearly fee for paid support."

"It is an open-source product."

"I have been working on the community edition."

"Pricing is significantly lower than competing products."

"EDB Postgres Advanced Server is open source, so I don't pay for licensing."
