Provides real-time data insights with high flexibility and responsive support
The basic challenge for ClickHouse is the documentation, which isn't ideal, but it's mature and stable with more columnar storage, compression, and parallel processing, making it the best for OLAP. 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.
Laksiri Bala - PeerSpot reviewer
Enhancing database learning with AI features and Oracle compatibility but needs performance improvements
I am a lecturer, and in universities, we use EDB Postgres Advanced Server to start with databases for practical purposes. I also assist with migrations, especially when clients want to migrate from Oracle to Postgres. So, while I am not a regular user, I am involved during migrations Since the…

Quotes from Members

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

Pros

"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."
"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 a user-friendly solution that tries to be compatible with SQL standards."
"The tool's most valuable feature is a database. It supports portal APIs and offers good flexibility."
"ClickHouse is open source with no vendor lock-in, providing excellent freedom to choose any vendor without restrictions."
"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."
"The tool is column-based and infinitely scalable."
"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."
"Postgres is highly compatible with many software and programming languages. Its compatibility is excellent, covering nearly everything related to data engineering or migration."
"The number of indices available in Postgres is remarkable."
"The feature of vector database management for AI is quite interesting and impactful."
"The low cost and functionality allows us to save money on smaller database projects."
"It gives us a solid, less expensive alternative to deploying with Oracle."
"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."
 

Cons

"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."
"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."
"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."
"I would like ClickHouse to work more on integration with third-party tools."
"ClickHouse has its own concept of database triggers and doesn't support traditional database triggers."
"We had a lot of troubles while deploying a whole cluster."
"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."
"The security is not very robust and the product would be much more useful with more security options."
"There aren't specific new features we wish to add."
"I would like to see improvements in the performance, especially in large-scale operations, as it currently cannot match Oracle's performance."
"The system is aging and not keeping up with the performance of new, enhanced database models."
"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."
 

Pricing and Cost Advice

"The tool is free."
"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."
"If you have an in-house deployment on Kubernetes or something, it's going to be very cheap since you'll be managing everything."
"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."
"We used the free, community version of ClickHouse."
"Pricing is significantly lower than competing products."
"EDB Postgres Advanced Server is open source, so I don't pay for licensing."
"I have been working on the community edition."
"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."
