Technical Architect at a tech services company with 11-50 employees

A fast and affordable solution that is scalable and has a nice dashboard

The product enables the users to query results faster. It maintains all the versions of the changes done on a specific node. A traditional blockchain would take time, but Amazon QLDB is a bit faster. We have to do many operations in blockchain to read data, but QLDB comes with an easy syntax. The product provides a nice dashboard to view all the information.

Quotes from Members

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

Pros

"The product enables the users to query results faster."

"The solution has good flexibility and very fast performance for searching data."

"MongoDB has many good replication features and good performance."

"It is easy to set up."

"It's super easy to develop a couple of solutions for clients with MongoDB, like a quick web page with no clear data structure that they need to spin up quickly to validate some sort of MDTP."

"like its performance and the stability. It's very stable and, performance-wise, it's really great."

"One of the first things I noticed when I had my first experience with MongoDB was how easy it was to use. I was expecting more difficulties or at least some challenges, but it was very, very easy to use. It's great technology, performs well, and is very convenient."

"I like the document storage feature. It's pretty simple."

"The solution is user-friendly with a good object retrieval feature."

More MongoDB pros

Cons

"The product should enable users to import data from various databases."

"Enhancing the documentation to make it more beginner-friendly is crucial."

"I'd like to see an ID generator. It's very technical but I don't think it has one, so we have to go to great lengths to work around that."

"It isn't easy to recognize entities with MongoDB."

"The transaction could use improvement. From MySQL, for example, you cannot create a transaction if you are reading and writing a document at the same time."

"The on-premises version of the solution is still pretty expensive, especially compared to the cloud version."

"I would recommend MongoDB as part of a template if anyone is considering free and open-source templating services such as LibreNMS, but as a standalone, I couldn't advise."

"The solution can be a bit tough to set up if you don't have knowledge about how the database works."

"Lacks sufficient scalability and elasticity."

More MongoDB cons

Pricing and Cost Advice

"The product is not expensive."

"If you want support with the solution you will need to purchase a license and not use the open-source version. The license is a little expensive."

"It's open-source."

"We are using the Community Edition of MongoDB."

"I'm using the free version of MongoDB."

"MongoDB's pricing is reasonable."

"MongoDB is a free solution. We wanted to have high availability and the subscription cost was quite expensive because the basic one is free and then when you want to have some other replications or other features you will need to pay money. Overall the solution is expensive."

"The product is affordable."

"The solution is open source so is free."
