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 provides great query speeds because it is an OLAP database, so naturally, it provides higher speeds."
"The tool is column-based and infinitely scalable."
"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 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's most valuable feature is a database. It supports portal APIs and offers good flexibility."
"ClickHouse has reduced our storage cost and improved our 99th percentile latency by 40%."
"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."
"It's easier to work with big data and calculations using the product."
"I appreciate the fact that, once the database is embedded, it doesn't need to be administered, and removes the requirement for a specific server."
"The solution is very useful for stock management."
"Firebird SQL is an open-source solution."
"The most valuable feature of the solution is that it is reliable, offers good performance, and is 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."
"Robustness is the absolutely main feature."
"We are happy with the event capabilities of Firebird SQL database. We can raise events from it and display them in our application."
"Firebird SQL is an open-source solution and can run on most operating systems, such as Linux, Unix, and Windows."
 

Cons

"ClickHouse could be improved further in several areas."
"We had a lot of troubles while deploying a whole cluster."
"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."
"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."
"I would like ClickHouse to work more on integration with third-party tools."
"The open-source version of ClickHouse is not very scalable."
"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."
"Database sharing is a capability that Firebird SQL lacks."
"It would be good to have more automation and integration with the tools from other vendors."
"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."
"It is not easy to integrate the tool with Visual Studio."
"We would like to improve the management of very large databases."
"I don't think the solution is very scalable, because the scalability of the performance when using more than one process is not very good."
"In the next release, it should support JSON, XML, and replication with third-party tools."
"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."
 

Pricing and Cost Advice

"ClickHouse has an open-source version, which is free to use and has almost all the features."
"The tool is open-source."
"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."
"ClickHouse Cloud is not expensive compared to other databases, costing a few dollars per month while providing fast performance."
"We used the free, community version of ClickHouse."
"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."
"There is a yearly maintenance fee for the use of the solution."
"There is no licensing cost for this solution, as it is open-source."
"The most valuable feature of the solution is that it is freely available."
"We are using the free solution, so there is no cost involved."
"It is okay."
"I was using the free version of Firebird SQL."
"It is a public domain system as every customer can install it on their system without paying any license fee."
