PavithrarajShetty - PeerSpot reviewer
Offers simplicity and is cheaply priced
I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.
Yasin Sarı - PeerSpot reviewer
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

"Postgres has some functions called JSONB aggregators or other aggregators, which are quite useful."
"It is easy to use."
"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."
"Initial setup is simple."
"Postgres is rock solid when deployed according to best practices as documented by the PostgreSQL community. When it's installed correctly, PostgreSQL is an enterprise-grade solution."
"The most valuable features are the price, stability, it is scalable and is used by our clients in small business environments, and it is a simple product to use."
"The product is very similar to the SQL Server."
"The tool is user-friendly."
"The most valuable feature is the ability to create pipelines, streamline and extract data from the pipelines."
"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 product can automatically reinstall and reconfigure in case of a shutdown."
"The paramount advantage is the exceptional speed."
"MemSQL supports the MySQL protocol, and many functions are similar, so the learning curve is very short."
"The ability to store data in memory is a standout feature, enhanced by robust failover mechanisms."
 

Cons

"There are several features I would like to improve that aren't working as expected. It's likely that the latest version is doing something that was missed in the previous versions. For example, the output parameters — the stored procedures — is something new in PostgreSQL that Firebird has already had for a long time."
"When you get a large number of records in a database and start doing various queries, it can adversely impact the performance of the live running systems. That's an area we continue to look at and mean to improve, but it is not only because of PostgreSQL. It is also because of the way the schemas are put together, and certain events are triggered. So, it is because of both parties."
"PostgreSQL’s performance could be improved."
"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"It could be more secure."
"The scalability is limited."
"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."
"I find it difficult to get connectors on the tool. For example, .NET has only one free provider in PostgreSQL. I need to pay the provider if I need something more sophisticated features. Other languages like PHP and Java have good community support. We need community support for .NET."
"Poor key distribution can significantly impact performance, requiring a backward approach in design rather than adding tables incrementally."
"We don't get good discounts in Pakistan."
"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."
"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."
"It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks."
 

Pricing and Cost Advice

"The tool is cheaply priced compared to other RDBMS providers in the market."
"It is also open-source so it is free."
"PostgreSQL is a free and open-source database."
"Affordable solution."
"There is an annual license."
"We do not pay for licensing."
"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."
"The community version of Postgre is basically free."
"I would advise users to try the free 128GB version."
"Using it for analytical purposes can be cost-effective in the long run, especially in terms of infrastructure."
"They have two main options: cloud installation and bare-metal installation, each with different pricing models."
"SingleStore is a bit expensive."
"The product's licensing is not expensive. It is comparable."
