Open-source freedom with efficient data handling and room for documentation growth
A significant area for improvement is the documentation, which is not comprehensive and lacks centralized resources, making it difficult to find information. Additionally, ClickHouse lacks robust support for transactional data, which limits its use as a primary database. My developer experience could be enhanced through better-organized documentation, perhaps by offering a cheat sheet or centralized guide for common setup and usage scenarios.
Umair Hassan - PeerSpot reviewer
Open-source and free to use with a good community
I would love to see the flashback in Percona MySQL or even in Percona PostgreSQL. It's available in Oracle, the flashback. In Oracle, there's the utility of a flashback. It stores all the information in the tables for a few days. That way, if I accidentally delete my records from the table or I need to check the value of a column or row two days back, I can. If Percona had flashback capabilities, it would be ideal. I would love to see training be easier to find. I had some complications finding the training that Percona provides. It is not displayed on the website. For example, if I want to train myself via a Percona expert through virtual files or through recorded videos or something like that, it's really difficult to find any sort of course. You have to email them first, and they will ask you whether it is for yourself or it is for the corporate sector. The course content should just be readily available and not hidden.

Quotes from Members

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

Pros

"The tool's most valuable feature is a database. It supports portal APIs and offers good flexibility."
"The main feature of ClickHouse is the optimizer because we had too many records to deduplicate, and the optimizer took this task by itself."
"ClickHouse is open source with no vendor lock-in, providing excellent freedom to choose any vendor without restrictions."
"It's easier to work with big data and calculations using the product."
"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 is a user-friendly solution that tries to be compatible with SQL standards."
"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."
"The tool is column-based and infinitely scalable."
"We find the product mostly stable."
 

Cons

"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."
"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."
"One issue is that you need persistent volumes. Otherwise, if one system goes down, you lose data in that cluster."
"There aren't too many improvements I'd suggest for ClickHouse as it covers all my needs. There are just a few technical issues. For example, sometimes, when you want to get unique values and use certain tables, they don't work as expected. But it's not a major problem."
"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."
"We had a lot of troubles while deploying a whole cluster."
"I would like ClickHouse to work more on integration with third-party tools."
"If Percona had flashback capabilities, it would be ideal."
 

Pricing and Cost Advice

"If you have an in-house deployment on Kubernetes or something, it's going to be very cheap since you'll be managing everything."
"The tool is free."
"ClickHouse has an open-source version, which is free to use and has almost all the features."
"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 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."
