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

"MongoDB is scalable and stable. The initial setup is very easy, and deployment and maintenance can be done by one person."
"MongoDB is relatively fast compared to relational databases."
"One of the biggest benefits is the speed and flexibility of the documents, especially when it comes to modifications."
"The solution has good flexibility and very fast performance for searching data."
"It is easy to use."
"I value the API integrations."
"MongoDB is easy to use."
"It has visible benefits, actually, in terms of price of ownership if you compare it to, for example, Oracle."
"The database is easy to use, fast, and accessible for applications because the API is straightforward."
"The performance aspects of Scylla are good, as always... A good point about Scylla is that it can be used extensively."
"The documentation is good. It integrates easily with our existing data infrastructure."
"ScyllaDB is fast and reliable. It has good performance."
"The product's most valuable features are efficiency and reliability."
"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!"
"It is lightweight, and it requires less infrastructure."
 

Cons

"We find it difficult to incorporate MongoDB in some projects."
"More stable indexes would be helpful in a future release. That's been an issue for some time. I don't know if it's been fixed now but we transitioned to it because we needed a search index to be able to search for things and if that goes or starts disappearing, we have to move away from that solution. I don't know if they fixed it, last time I had this issue was three years ago so they might have solved it."
"Simplifying the aggregation framework would be an improvement."
"MongoDB could improve by not having so many updates and different versions."
"I rate the support from MongoDB a four out of five."
"The solution could include more integrations with other platforms."
"A normal Oracle or database tester will take some time to gear up to MongoDB because the way of writing queries is different in MongoDB. There should be some kind of midway where a person who is coming from an Oracle background can write a query and get a response by using something like a select * statement or other such things. There should be some way for MongoDB to interpret these commands rather than making a person learn MongoDB commands and writing them. I struggled while writing these MongoDB commands. I had not seen such queries before. It was pretty difficult to get them. This is one of the areas where it would help from the improvement standpoint."
"The dashboard is an area of concern in the solution where improvements are required."
"ScyllaDB needs to improve its handling of transactions."
"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."
"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."
"Some of the regular commands in NoSQL do not work."
"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

"Our customers pay for yearly licenses for MongoDB."
"It's a community edition, so we do not pay anything."
"MongoDB is a bit expensive compared to its competitors."
"The solution is open source, so it is free."
"MongoDB's pricing is reasonable."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"MongoDB's pricing is not reasonable, but it is not as expensive as the others."
"We are using the Community Edition of MongoDB."
"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."
"It is an expensive tool compared to its competitor."
"It's a bit expensive."
"It's free."
