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

"It has visible benefits, actually, in terms of price of ownership if you compare it to, for example, Oracle."
"One of the biggest benefits is the speed and flexibility of the documents, especially when it comes to modifications."
"It is really a pretty easy product to use. It's very reliable, it's proven."
"One of the most valuable features is the ability to Text Search can be used anywhere and anytime."
"It's easy to add and remove things in MongoDB. You can alter the tables. MongoDB is faster at reading, slower at writings."
"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."
"MongoDB is a NoSQL tool that gives us much freedom to manipulate how the data works."
"The community is great if you have problem."
"The documentation is good. It integrates easily with our existing data infrastructure."
"The database is easy to use, fast, and accessible for applications because the API is straightforward."
"Firstly, if I update something, it's most likely to finish within milliseconds."
"I like how fast it is to query data from the ScyllaDB node!"
"ScyllaDB is very fast, and I can use it for so many things."
"The product's most valuable features are efficiency and reliability."
"ScyllaDB is fast and reliable. It has good performance."
"The performance aspects of Scylla are good, as always... A good point about Scylla is that it can be used extensively."
 

Cons

"We'd like technical support to respond faster to queries."
"MongoDB could be more secure."
"The user interface is not as friendly as Oracle, which is something that can be improved."
"Data encryption is possible using third-party tools but they should have their own encryption capability built-in to this solution."
"Simplifying the aggregation framework would be an improvement."
"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."
"It could be much more flexible like SequoiaDB. I would like to see more flexibility in the next release, especially when working with Microsoft Windows. A lot of people struggle with MongoDB because of their Windows versions. But Linux is faultless and mostly runs nicely."
"MongoDB can improve large-size video or media frame operations. There are a lot of customers who want to upload media frames and video games but there is some difficulty. In MongoDB, we are looking out for solutions that are for large-size media files that can be saved and navigated efficiently."
"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."
"The product needs to add more features and improve the response time of the support team."
"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 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."
"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."
 

Pricing and Cost Advice

"This is an open-source 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."
"It's a community edition, so we do not pay anything."
"If you want support with the solution you will need to purchase a license and not use the open-source version. The license is a little expensive."
"MongoDB's pricing is reasonable."
"I believe that MongoDB is free."
"The solution is open source so is free."
"It is an expensive tool compared to its competitor."
"It's free."
"It's a bit 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."
"I believe that there is a yearly licensing cost and that it's expensive."
