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.

An excellent choice for diverse data processing needs with exceptional in-memory capabilities, robust failover mechanisms, easy scalability and high performance
Scalability is its key strength. Adding servers for scalability is a straightforward process involving simply incorporating a few additional servers and recycling the cluster triggers automatic repartitioning and redistribution of data. For instance, if the initial database creation involved a hundred servers and later, four more servers are added, specific commands can be executed to increase the partitions to one hundred twenty. The data is then efficiently redistributed across the expanded partitions without the need for manual data movement, ensuring a seamless and efficient scalability process. In my current organization, approximately three projects involve the usage of SingleStore, with a team size ranging from ten to twenty individuals.

Quotes from Members

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

Pros

"PostgreSQL is very easy to use. I have experience in Oracle SQL and PostgreSQL uses the same syntax which makes it is easy for me to develop."
"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."
"Scalable, stable, and easy to manage database system, with a straightforward installation."
"We managed to reduce the storage space needed to 10% of the original size, without affecting data integrity, and we significantly improved the performance."
"What I like is that it's quite powerful in terms of performance."
"It's a useful solution, that can be widely used."
"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."
"The solution is scalable, it is very good."
"The most valuable feature is the ability to create pipelines, streamline and extract data from the pipelines."
"The product can automatically reinstall and reconfigure in case of a shutdown."
"The ability to store data in memory is a standout feature, enhanced by robust failover mechanisms."
"The paramount advantage is the exceptional speed."
"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."
"MemSQL supports the MySQL protocol, and many functions are similar, so the learning curve is very short."
 

Cons

"A better graphic user-interface would be nice to see."
"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."
"If it was free to use, it would be the perfect solution."
"PostgreSQL is a stable system, but from a security point of view, it still needs improvement."
"We often find the solution's datetime datatype challenging."
"I'm not really able to customize it."
"Integration with other platforms could be improved."
"PostgreSQL could improve by adding data warehousing tools."
"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."
"It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks."
"There should be more pipelines available because I think that if MemSQL can connect to other services, that would be great."
"Having the ability to migrate servers using a single command would be extremely beneficial."
"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

"We are using the free version of PostgreSQL."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"It is also open-source so it is free."
"We do not pay for licensing."
"There is an annual license."
"Affordable solution."
"The need for our customers to pay for licences is contingent on their projects and budgets."
"This solution can offer a cheaper choice for customers since it is open-source."
"Using it for analytical purposes can be cost-effective in the long run, especially in terms of infrastructure."
"I would advise users to try the free 128GB version."
"SingleStore is a bit expensive."
"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."

Questions from the Community

How does Firebird SQL compare with PostgreSQL?
PostgreSQL was designed in a way that provides you with not only a high degree of flexibility but also offers you a cheap and easy-to-use solution. It gives you the ability to redesign and audit yo...
What do you like most about PostgreSQL?
It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping.
What is your experience regarding pricing and costs for PostgreSQL?
The tool is free of cost. For now, it's not about making money. But once we perfect it, we can offer it to customers willing to pay for support and other services. Most of my deployments are free.
