High-speed data processing, seamless scalability, and excellent high availability making it an optimal choice for those prioritizing performance and efficiency in a database solution

There's a noteworthy consideration when it comes to collecting massive amounts of data. It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks. Attempting to use it for direct extraction, for instance, might lead to memory-related challenges. While MySQL version five might lack extensive SQL capabilities, SingleStore also has its constraints, requiring simpler SQL writing. This becomes evident when seeking advanced functionalities like window functions or JSON functions, where SingleStore doesn't offer an extensive toolkit, necessitating a more straightforward approach to SQL.

Quotes from Members

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

Pros

"The most valuable feature is PowerPC support."

"The most valuable features are with the industrial side."

"it is very stable and runs smoothly once it is deployed and it is almost maintenance-free."

"The structure is straightforward, consisting of the test file and the logical and physical files. You have one physical file and many logical files related to it."

"Reliable, robust with great features."

"I can easily export that to further work on it in Snowflake."

"As part of your licensing with IBM, you get access to their case system, which lets you raise incidents related to software or hardware. This system is helpful for problem determination and quickly identifying issues."

"The solution's initial setup is straightforward."

More IBM Db2 Database pros

"The product can automatically reinstall and reconfigure in case of a shutdown."

"It's a distributed relational database, so it does not have a single server, it has multiple servers. Its architecture itself is fast because it has multiple nodes to distribute the workload and process large amounts of data."

"The most valuable feature is the ability to create pipelines, streamline and extract data from the pipelines."

"The ability to store data in memory is a standout feature, enhanced by robust failover mechanisms."

"MemSQL supports the MySQL protocol, and many functions are similar, so the learning curve is very short."

"The paramount advantage is the exceptional speed."

Cons

"The pricing could be improved, it's expensive."

"The backup solution lacks flexibility."

"They should develop its containerized version."

"The solution's UI hasn't been upgraded. The solution’s UI is an area to improve because the solution was developed long ago."

"There are some issues with Db2's database file system not being readable. The storage could also be increased, and the monitoring could be improved."

"Do not use support. Freely available documentation is a bit weak."

"Db2 interface could be improved a bit. Comparing it to Oracle, Db2's interfaces could be improved."

"IBM's support isn't as strong as it used to be, especially when it comes to providing fixes."

More IBM Db2 Database cons

"Having the ability to migrate servers using a single command would be extremely beneficial."

"There should be more pipelines available because I think that if MemSQL can connect to other services, that would be great."

"We don't get good discounts in Pakistan."

"It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks."

"For new customers, it's very tough to start. Their documentation isn't organized, and there's no online training available. SingleStore is working on it, but that's a major drawback."

"Poor key distribution can significantly impact performance, requiring a backward approach in design rather than adding tables incrementally."

Pricing and Cost Advice

"It is expensive."

"We purchase the product's yearly license."

"I rate the price of the IBM Db2 Database an eight out of ten."

"It is expensive. The price depends on the size of the machine on which you are installing the Db2 and the features you are using. It also depends on the country. IBM has different policies and different options for payment for this product."

"Among Microsoft SQL Server, Oracle, and Db2, Microsoft SQL Server is the cheapest one, and Oracle is the most expensive one. Db2 is in the middle. As compared to SQL Server, its price could go down. It will be good for customers."

"Compared to Oracle, it is so much cheaper."

"Db2 is less expensive than Oracle."

"I rate the product pricing a nine out of ten."

More IBM Db2 Database pricing and cost advice

"The product's licensing is not expensive. It is comparable."

"They have two main options: cloud installation and bare-metal installation, each with different pricing models."

"Using it for analytical purposes can be cost-effective in the long run, especially in terms of infrastructure."

"SingleStore is a bit expensive."

"I would advise users to try the free 128GB version."
