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.

An open-source database to hold customer data, but its performance should be improved
Firebird SQL significantly improved our data management in many parts of our self-developed ERP system. I rate the solution's performance and speed a six out of ten. Two or three database administrators are needed to maintain the solution. A few years ago, migrating data to or from Firebird SQL was a little bit difficult because the identifier names for tables or stored procedures were limited to 20 to 30 characters. Transferring the structure to Firebird SQL was difficult, but they fixed it in version 3, which was much easier. We are developing software with Delphi, and Delphi is also by Embarcadero. Using InterBase or Firebird SQL databases is very common, and you have some good tools for developing with Firebird SQL. Overall, I rate the solution a seven out of ten.

Quotes from Members

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

Pros

"ClickHouse has reduced our storage cost and improved our 99th percentile latency by 40%."
"ClickHouse provides responses within a few seconds, typically two to three seconds, which is impressive."
"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."
"ClickHouse is a user-friendly solution that tries to be compatible with SQL standards."
"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."
"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."
"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."
"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 documentation is very well written."
"It helps us in detecting all kinds of problems in the code, such as bad quality, unclear code, or any violation in the code or best practices."
"The product was easy to use."
"I like that we don't have to pay external fees to migrate this data. So, we are looking to relocate from Postgres or EDB."
"The reliability and ease of management are very valuable."
"I can deploy it on Linux, Mac OS, and Windows — it's very easy."
"We are happy with the event capabilities of Firebird SQL database. We can raise events from it and display them in our application."
"The most valuable feature of the solution is that it is reliable, offers good performance, and is easy to use."
 

Cons

"In terms of needed improvements, some enhancements in documentation are necessary."
"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."
"ClickHouse has its own concept of database triggers and doesn't support traditional database triggers."
"One issue is that you need persistent volumes. Otherwise, if one system goes down, you lose data in that cluster."
"ClickHouse could be improved further in several areas."
"The main issue is the lack of documentation. Many features are available but are not fully documented, which can make finding information challenging."
"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."
"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."
"This solution isn't very user-friendly, or intuitive, which could be improved when it is developed."
"On large databases, we have some difficulties."
"It would be interesting if they added functionality with redundancy, reputation, and variability."
"We would like to improve the management of very large databases."
"Database sharing is a capability that Firebird SQL lacks."
"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."
"In the next release, it should support JSON, XML, and replication with third-party tools."
"The solution could improve by providing partitioning and encryption. It is not at the higher level of database solution but it could be with some upgrades."
 

Pricing and Cost Advice

"The tool is open-source."
"We used the free, community version of ClickHouse."
"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 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."
"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."
"It's open-source and free."
"There is no licensing cost for this solution, as it is open-source."
"The tool is open source."
"It is a public domain system as every customer can install it on their system without paying any license fee."
"Firebird SQL is an open-source solution, which means it is a free product."
"There is a yearly maintenance fee for the use of the solution."
"The most valuable feature of the solution is that it is freely available."
"I was using the free version of Firebird SQL."
