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

"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."

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

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

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

"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 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."

More ClickHouse pros

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

"The product is user-friendly."

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

"EDB Postgres Advanced Server has positively impacted my organization by being cost-saving compared to databases such as Oracle, while providing smooth performance that simplifies production operations with less downtime and effort, especially in a cloud environment where we can utilize containerized services."

"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."

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

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

"I would highly recommend EDB Postgres Advanced Server to others."

Cons

"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."

"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."

"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."

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

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

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

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

More ClickHouse cons

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

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

"For improvement purposes, I think EDB Postgres Advanced Server needs some enhanced monitoring since the current default monitoring is not sufficient; an EDB monitoring tool could provide useful metrics to help end users avoid production issues."

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

"Postgres performance is suffering and the product model is not doing enough to keep current."

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

"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."

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

Pricing and Cost Advice

"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."

"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."

"The tool is free."

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

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

"I have been working on the community edition."

"It is an open-source product."

"Pricing is significantly lower than competing products."

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