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.

Database Engineer at a tech vendor with 1-10 employees

Centralized management has reduced database overhead but pricing and documentation have needed work

What I appreciate about EDB Postgres Advanced Server is that it offers management tools such as PEM and CNPG under one umbrella, providing enterprise features that eliminate the need for multiple engineers to maintain PostgreSQL databases, although it is somewhat expensive. I evaluate the technical support and customer service of EDB Postgres Advanced Server as really good, as I have sought their help three to four times regarding issues with PEM configuration, and they respond quickly and solve issues promptly. I would rate the technical support of EDB Postgres Advanced Server an 8 out of 10. EDB Postgres Advanced Server's high availability and disaster recovery features, specifically the introduction of CNPG based on Kubernetes, are good, but they require significant infrastructure overhead, which I believe necessitates a lightweight integration model for better performance. I rate the efficiency improvements from EDB Postgres Advanced Server a 10 out of 10 when it comes to Oracle compatibility. Its native support for Oracle's PL/SQL syntax makes evaluating and migrating legacy workloads incredibly smooth, bypassing the typical headaches of manual code rewrites.

Quotes from Members

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

Pros

"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."

"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."

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

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

"ClickHouse has positively impacted my organization by replacing PostgreSQL, which required complex foreign tables for queries, and with ClickHouse we now have Cube.js for easier data visualization."

"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."

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

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

More ClickHouse pros

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

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

"Cost/benefit wise Postgres is a great solution."

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

"Major reduction in run cost, and a quantum leap in the flexibility of deployment models Elimination of replication of transaction from reporting systems Able to do rolling upgrades with zero production downtime."

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

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

"The product is user-friendly."

Cons

"There are some areas where ClickHouse could improve. Specifically, we encountered incompatibilities with its SQL syntax when migrating queries from MySQL or SQL to ClickHouse. This difference in details made it challenging to figure out the exact issues. Additionally, we faced difficulties due to the lack of a proper Django driver for ClickHouse, unlike MySQL, which Django supports out of the box."

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

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

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

"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 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."

"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."

More ClickHouse cons

"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 lack of additional security features is really the thing that makes the product less useful."

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

"From a pricing perspective, I do not find it cost-effective from DBtune's SaaS perspective as we are just testing it, but for enterprises, it is worth it as you do not require many engineers for management and receive good support."

"It suffers issues ranging from data corruption to failing to delete temporary files which then necessitate us having to perform server restarts."

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

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

"Lighter integration model for containerized deployment. Effectively, there still remain some issues with a containerized deployment, so we have opted for a non-containerized deployment."

Pricing and Cost Advice

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

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

"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."

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

"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."

"Pricing is significantly lower than competing products."

"I have been working on the community edition."

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