Hamidul Islam - PeerSpot reviewer
Lightweight with good flexibility and very fast performance for searching data
I used the solution in the production level to search data and create education-based tutorials for a project. We had 30 managers, senior architects, tech leads, and software engineers working on the project.  Currently, I use the solution for my personal work.  The solution has good flexibility…
Manikandan Gunasekaran - PeerSpot reviewer
Reliable data management with great reliability and performance
From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction. Additionally, ticketing and support systems could be improved due to the time it takes to get answers. There's also an issue with compatibility when attempting to switch back from the enterprise to the community version.

Quotes from Members

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

Pros

"Its flexibility, and cost. It is reasonably priced."
"The installation is very easy to do and understand."
"MongoDB is highly stable, and I would rate its stability at nine out of ten."
"The solution's most important aspect is its seamless database."
"I like the document storage feature. It's pretty simple."
"like its performance and the stability. It's very stable and, performance-wise, it's really great."
"MongoDB is a NoSQL tool that gives us much freedom to manipulate how the data works."
"The aggregation framework is very powerful when elaborating on data."
"The performance and scalability are good, and we hardly see any major issues with ScyllaDB."
"The database is easy to use, fast, and accessible for applications because the API is straightforward."
"I like how fast it is to query data from the ScyllaDB node!"
"ScyllaDB is fast and reliable. It has good performance."
"Firstly, if I update something, it's most likely to finish within milliseconds."
"The documentation is good. It integrates easily with our existing data infrastructure."
"It is lightweight, and it requires less infrastructure."
"The product's most valuable features are efficiency and reliability."
 

Cons

"Enhancing the documentation to make it more beginner-friendly is crucial."
"Our program developer finds it to be a little unstable, development-wise."
"It would be good to have scalability for clusters. For example, if we have three clusters, we should be able to increase to five clusters if required. I am not sure if such a feature is currently there. I hope there is good documentation for this."
"They could improve the UI and the analytics part."
"There are some problems with bugs appearing in sharding when the data is too high."
"MongoDB should incorporate more features, particularly search functionality, and real-time communication capabilities, to improve the database and provide data listening services. Currently, we rely on the Atlas offering, but it would be fantastic if MongoDB could develop a new solution or updated version that includes these features within its internal database and driver. However, I am uncertain if this would be a viable or profitable move for them, and I am speaking from a mobile-centric viewpoint."
"I feel that most people don't know a lot about MongoDB, so maybe they could add some more documentation and tutorials."
"The performance can be improved."
"From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction."
"If you don't have the best computing resources, then it's not easy to set up. In such cases, we have to run ScyllaDB in developer mode."
"Data export, along with how we can purchase the data periodically, needs to be improved so that the storage is within control. Then, we could optimize it even better."
"We faced several challenges while integrating ScyllaDB into our AWS environment. One common issue was that a security port wasn’t opened on one node, preventingdata synchronization across clusters. We noticed the data wasn’t syncing correctly when we saw different record counts in other regions. After investigating, we found that the port was closed in one AWS region. Once we opened the port, the data synchronization across all nodes resumed as expected."
"ScyllaDB needs to improve its handling of transactions."
"The documentation of Scylla is an area with shortcomings and needs to be improved."
"The documentation is not well established for new developers."
"It seems we have better options available. So probably don't go for ScyllaDB. The reason is, first, it's very high. It's not as straightforward as, like, Postgres or ClickHouse to set up. It requires a complex setup."
 

Pricing and Cost Advice

"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."
"I believe that the licensing fees are paid on a yearly basis."
"I only used the open-source version."
"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"You only have to pay for the paid version, not the open-source version."
"I believe that MongoDB is free."
"At the moment, all customers are using the community version."
"We use the open-source version, which is available to use free of charge."
"The paid version of ScyllaDB is not that expensive. The main advantage of the paid version is direct support from the ScyllaDB team, which can resolve issues faster—typically within a day, compared to two to three days with the free version. The paid version also offers better guidance and support, while the free version has good documentation and is more high-level. I’d rate their support team nine out of ten because of the quick responses from their community."
"I believe that there is a yearly licensing cost and that it's expensive."
"It is an expensive tool compared to its competitor."
"It's free."
"It's a bit expensive."
