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 think that MongoDB isn't too structured, and that's good for our technical team because they are able to search through the database better than if they are using SQL Server."
"MongoDB is extremely developer-friendly because when you are starting, there is very little time needed upfront in terms of planning."
"The most valuable feature is the geometric information done with GeoJSON."
"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."
"It is a stable solution. Stability-wise, I rate the solution a nine out of ten...Overall, MongoDB has helped manage and analyze attachment data."
"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."
"The most valuable feature is that you can store unstructured data, which is helpful when you don't know what the best structure should be and you cannot use a relational database because of that."
"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."
"Firstly, if I update something, it's most likely to finish within milliseconds."
"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."
"I like how fast it is to query data from the ScyllaDB node!"
"The database is easy to use, fast, and accessible for applications because the API is straightforward."
"ScyllaDB is fast and reliable. It has good performance."
"ScyllaDB is very fast, and I can use it for so many things."
"The documentation is good. It integrates easily with our existing data infrastructure."
 

Cons

"Sometimes, the tool goes down temporarily. There are some stability issues in the product."
"I don't see a lot of areas that need improvement."
"The performance can be improved."
"The dashboard is an area of concern in the solution where improvements are required."
"They could provide more documentation and examples for adding pipeline stages."
"From my point of view, they need a totally free IDE to work at high levels."
"MongoDB should be more stable, and support should be more efficient."
"I think it would be good to have more search options such as an index resource. This will provide more options and resources to do advance searches."
"The product needs to add more features and improve the response time of the support team."
"Some of the regular commands in NoSQL do not work."
"ScyllaDB needs to improve its handling of transactions."
"The documentation is not well established for new developers."
"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."
"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."
"The documentation of Scylla is an area with shortcomings and needs to be improved."
"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

"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"It's open-source."
"It is rather expensive."
"MongoDB is not expensive."
"Our customers pay for yearly licenses for MongoDB."
"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."
"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"MongoDB's pricing is reasonable."
"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."
