Transforms data flow with adaptable schema and smooth public cloud deployment
One of our business units uses MongoDB, and we developed an ETL pipeline that extracts data from MongoDB and transfers it into our data warehouse MongoDB is a NoSQL database that is similar to a document database. It offers flexibility in schema adaptation, allowing us to change the schema and…

Offers encryption and supports APIs, making it great for distributed systems
The best features of ScyllaDB are how it synchronizes data and its failover system. There's a unique formula to decide the number of nodes you need and the minimum required, which I find helpful. It also offers encryption and supports APIs, making it great for distributed systems and scaling databases across different regions. While it's easy to use, having prior experience helps configure it properly. There are many configurations; if you don't understand them, you might mess up the design. So, understanding your system's needs, like whether it requires more read or write operations, is crucial for setting up the correct configuration.

Quotes from Members

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

Pros

"I like the schemaless architecture that it follows. I also like the sharding that it provides."
"One of the most valuable features is the ability to Text Search can be used anywhere and anytime."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
"The solution's most important aspect is its seamless database."
"I found that MongoDB is most valuable for storing school-related queries. It's also user-friendly, and I found no difficulty accessing it. Setting it up is easy too."
"The most valuable feature of MongoDB is the NoSQL database. In a SQL database, we need to join data together with a unique ID amongst other things, but in MongoDB, it's not required. We can directly receive all the information. The performance is very good. Additionally, they have frequent updates."
"It is really a pretty easy product to use. It's very reliable, it's proven."
"The installation is very stable."
"The product's most valuable features are efficiency and reliability."
"ScyllaDB allows fine-tuning of the table structure. Speed is probably the most critical factor because we perform a lot of heavy data ingestion. One of its core features is its ability to handle high volumes and maintain speed when accessing data. Additionally, high availability and partitioning are built-in features of ScyllaDB."
"The performance and scalability are good, and we hardly see any major issues with ScyllaDB."
"It is lightweight, and it requires less infrastructure."
"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."
"The best features of ScyllaDB are how it synchronizes data and its failover system. There's a unique formula to decide the number of nodes you need and the minimum required, which I find helpful. It also offers encryption and supports APIs, making it great for distributed systems and scaling databases across different regions. While it's easy to use, having prior experience helps configure it properly. There are many configurations; if you don't understand them, you might mess up the design. So, understanding your system's needs, like whether it requires more read or write operations, is crucial for setting up the correct configuration."
"I like how fast it is to query data from the ScyllaDB node!"
 

Cons

"Enhancing the documentation to make it more beginner-friendly is crucial."
"Some of the solution's transaction capabilities can be improved."
"It could be more stable. It would be better if it were more user-friendly like Oracle, which is very easy. For example, creating an index is simple in Oracle. In MongoDB, it's quite challenging to do that. Performance could be better. It's fast and good, but you cannot put every application that you would like to in MongoDB."
"MongoDB should not be used for reporting, analytics, or number-crunching tasks."
"Actually, with MongoDB, it's difficult to calculate the return on investment; it's too expensive for our use."
"MongoDB could improve by not having so many updates and different versions."
"There should be better integration with other databases."
"The scalability of the solution has room for improvement."
"ScyllaDB needs to improve its handling of transactions."
"From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction."
"Some of the regular commands in NoSQL do not work."
"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."
"The product needs to add more features and improve the response time of the support team."
"The documentation of Scylla is an area with shortcomings and needs to be improved."
"The documentation is not well established for new developers."
"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."
 

Pricing and Cost Advice

"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"There is an annual subscription for the use of this solution."
"I only used the open-source version."
"There is an enterprise license and it could be cheaper. We are using the free open source version."
"The pricing is favorable if you opt to install MongoDB on an Amazon EC2 instance as you won't have to pay for the extra Atlas services and can instead manage the scaling yourself. This allows for a cost-effective solution and using MongoDB on a small scale, I have been able to utilize it for free."
"It's open-source."
"MongoDB is an open-source product."
"We are using the Community Edition of MongoDB."
"It is an expensive tool compared to its competitor."
"I believe that there is a yearly licensing cost and that it's expensive."
"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."
"It's a bit expensive."
"It's free."
