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

"It facilitates the generation of heatmaps for graphical data analysis."
"MongoDB is scalable and stable. The initial setup is very easy, and deployment and maintenance can be done by one person."
"We've found the product to be scalable."
"The reports are useful for controlling the load of our whole architecture."
"The solution's most important aspect is its seamless database."
"It stores historical data with ease. For example, if you are a healthcare member, then you will have multiple records of visits to the doctors. To store such data in Oracle Database, you have to create many records. You might also have duplication problems because your records are going in again and again, because of which the data warehouse and the maintenance cost will be huge. MongoDB is comparatively lightweight. It is a JSON extract. Once you define a schema and extract it, you can push all the relationships in any way you want. It is easier to define and get different types of transactions into MongoDB. It is also easier to set it up as compared to other solutions. MongoDB is a NoSQL database, which means it is a document DB in which you can store documents that you created in BSON. It is pretty fast in response. It is faster than relational databases because it does not define any primary keys, secondary keys, tertiary keys, and all those kinds of things."
"MongoDB is a NoSQL tool that gives us much freedom to manipulate how the data works."
"We can define security rules at the database level or the cluster level to grant or deny access to particular users."
"ScyllaDB is very fast, and I can use it for so many things."
"I like how fast it is to query data from the ScyllaDB node!"
"The performance and scalability are good, and we hardly see any major issues with ScyllaDB."
"Firstly, if I update something, it's most likely to finish within milliseconds."
"The performance aspects of Scylla are good, as always... A good point about Scylla is that it can be used extensively."
"ScyllaDB is fast and reliable. It has good performance."
"It is lightweight, and it requires less 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.

So, understanding your system's needs, like whether it requires more read or write operations, is crucial for setting up the correct configuration."
 

Cons

"From my point of view, they need a totally free IDE to work at high levels."
"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."
"MongoDB should be more stable, and support should be more efficient."
"MongoDB is a very useful and convenient choice, but sometimes for more complex projects, there are certain niche requirements that appear, so using a different tool could be beneficial. It raises the complexity of the architecture, but it could be beneficial to the world, the features, the ease of the features which are being implemented."
"The scalability of the solution has room for improvement."
"It would help if MongoDB offered a light solution for small projects."
"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."
"The product's data consistency could be more efficient than traditional SQLs."
"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 documentation of Scylla is an area with shortcomings and needs to be improved."
"ScyllaDB needs to improve its handling of transactions."
"From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction."
"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."
"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."
"The documentation is not well established for new developers."
 

Pricing and Cost Advice

"It is rather expensive."
"MongoDB's pricing is reasonable."
"The solution is open source so is free."
"I currently use the solution's community edition which is free."
"Our customers pay for yearly licenses for MongoDB."
"We are using the Community Edition of MongoDB."
"MongoDB is an open-source product."
"This is an open-source solution."
"It's free."
"I believe that there is a yearly licensing cost and that it's expensive."
"It is an expensive tool compared to its competitor."
"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."
