Real-time data capture optimizes database performance but Views create problems
One of the most valuable features is real-time data capture; it optimizes database performance. I think using real-time data capture reduces job running time and the amount of data sent at once with batch loads. Replicating the same data daily isn't optimal, so real-time reception improves application performance and reduces latency.

Supports in-memory data types, storing data on RAM for high performance
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. Also, technically, SingleStore needs more features on the SQL part. Most SQL boards work in MySQL, and SingleStore integrated all its sequel with MySQL, so nearly 99% of MySQL code runs on SingleStore. But features like TVF and UDL lack depth. Users have to walk into it, and SingleStore has minimal features there. IUDF, TVF, and stored procedures are not as advanced as SQL Server's. That's one thing I would like to see improved.

Quotes from Members

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

Pros

"It is a pretty comprehensive database system. Its performance is good, and it does what it is supposed to do. It also integrates very well."
"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."
"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."
"It's a useful solution, that can be widely used."
"It has completely met our needs. It works, and it is robust. We haven't had any problems with what PostgreSQL does for us and the way it does it. That's why we've been using it for so long. We understand it, and it does the job."
"The solution has many valuable features such as it easy to use and the interface is intuitive."
"It is very simple to manage."
"The product is easy to use and works fast for relational databases."
"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."
"MemSQL supports the MySQL protocol, and many functions are similar, so the learning curve is very short."
"The paramount advantage is the exceptional speed."
"The ability to store data in memory is a standout feature, enhanced by robust failover mechanisms."
 

Cons

"They need to improve the user experience of the management."
"Sometimes, it becomes slow because of the network. So, there is room for improvement in performance."
"We have to set up event API, which takes a lot of events from the user."
"It needs more integration."
"The price could be better."
"Instead of the installation agent downloading all the packages for the install, it should allow the user to download the packages separately on their own to do the install."
"It would be great if the solution offered even more integration capabilities."
"I have noticed that user and access management should be improved."
"There should be more pipelines available because I think that if MemSQL can connect to other services, that would be great."
"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."
"Having the ability to migrate servers using a single command would be extremely beneficial."
"It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks."
"We don't get good discounts in Pakistan."
"Poor key distribution can significantly impact performance, requiring a backward approach in design rather than adding tables incrementally."
 

Pricing and Cost Advice

"It is free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."
"Affordable solution."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"It is an open-source platform."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"We are using the free version of PostgreSQL."
"The licensing model is good."
"The community version of Postgre is basically free."
"SingleStore is a bit expensive."
"Using it for analytical purposes can be cost-effective in the long run, especially in terms of infrastructure."
"The product's licensing is not expensive. It is comparable."
"I would advise users to try the free 128GB version."
"They have two main options: cloud installation and bare-metal installation, each with different pricing models."
