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.
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

"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 main feature of ClickHouse is the optimizer because we had too many records to deduplicate, and the optimizer took this task by itself."
"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."
"It's easier to work with big data and calculations using the product."
"The tool is column-based and infinitely scalable."
"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."
"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."
"We find the product mostly stable."
 

Cons

"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."
"One issue is that you need persistent volumes. Otherwise, if one system goes down, you lose data in that cluster."
"I would like ClickHouse to work more on integration with third-party tools."
"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."
"The main issue is the lack of documentation. Many features are available but are not fully documented, which can make finding information challenging."
"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."
"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."
"We had a lot of troubles while deploying a whole cluster."
"If Percona had flashback capabilities, it would be ideal."
 

Pricing and Cost Advice

"ClickHouse has an open-source version, which is free to use and has almost all the features."
"ClickHouse Cloud is not expensive compared to other databases, costing a few dollars per month while providing fast performance."
"The tool is open-source."
"The tool is free."
"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."
