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…

Self-hosting complexity and the way ScyllaDB counts operations can be confusing and may not reflect actual usage
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 other problem is what they call. For example, they will say that for up to a million operations, you experience this. But the problem is if they have nine servers, then your one operation is counted as nine operations, not one. So, even though you have one write, they count it as nine. It's like it's just not false premises. You can always host it yourself, but then it's way more complex. The benefits are not substantially more than those of other databases. It's not that it's slow or anything. It's good enough and all. But it's just that ClickHouse or other databases are simpler and faster and probably provide more features. So, I kind of burn out from the database, and that's why I would keep it small.

Quotes from Members

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

Pros

"The solution does not hold data in tabular format like SQL does but rather clusters data so that it can link on a large scale."
"The integration capabilities of MongoDB are fine for the solutions that we use in our company."
"MongoDB's approach to handling data in documents rather than traditional tables has been particularly beneficial."
"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 clustering is very good. It allows us to have high availability."
"The geospatial index feature is useful for dealing with latitude and longitude data."
"It is easy to set up."
"The Dynamic Application is a valuable feature."
"The documentation is good. It integrates easily with our existing data infrastructure."
"It is lightweight, and it requires less infrastructure."
"The database is easy to use, fast, and accessible for applications because the API is straightforward."
"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."
"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."
"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."
 

Cons

"The solution should more easily integrate with custom code."
"The user interface is not as friendly as Oracle, which is something that can be improved."
"From my point of view, they need a totally free IDE to work at high levels."
"There was a need for integrating relational database capabilities, however, MongoDB has introduced a relational converter that allows conversion between SQL and NoSQL."
"The stability could be improved."
"The performance could be faster."
"The improvements could be made to intelligence to detect disk storage and prevent MongoDB from crashing."
"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."
"ScyllaDB needs to improve its handling of transactions."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"Our customers pay for yearly licenses for MongoDB."
"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"I only used the open-source version."
"It's a community edition, so we do not pay anything."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"This is an open-source solution."
"I believe that MongoDB is free."
"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 is an expensive tool compared to its competitor."
"It's a bit expensive."
"It's free."
"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."
